The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped by Red Hat.\n\nAn integer signedness error in the ASN.1 decoder before version 1.2.5\nallows remote attackers to cause a denial of service via a large unsigned\ndata element length, which is later used as a negative value.  The Common\nVulnerabilities and Exposures project has assigned the name CAN-2002-0036\nto this issue.  \n\nThe Key Distribution Center (KDC) before version 1.2.5 allows remote,\nauthenticated, attackers to cause a denial of service (crash) on KDCs\nwithin the same realm via a certain protocol request that:\n\n- causes a null pointer dereference (CAN-2003-0058).\n\n- causes the KDC to corrupt its heap (CAN-2003-0082).\n\nA vulnerability in Kerberos before version 1.2.3 allows users from\none realm to impersonate users in other realms that have the same\ninter-realm keys (CAN-2003-0059).\n\nThe MIT advisory for these issues also mentions format string\nvulnerabilities in the logging routines (CAN-2003-0060).  Previous versions\nof the kerberos packages from Red Hat already contain fixes for this issue.\n\nVulnerabilities have been found in the implementation of support for\ntriple-DES keys in the implementation of the Kerberos IV authentication\nprotocol included in MIT Kerberos (CAN-2003-0139).\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nwhich allow an attacker with knowledge of a cross-realm key that is shared\nwith another realm to impersonate any principal in that realm to any\nservice in that realm.  This vulnerability can only be closed by disabling\ncross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5.  A faulty length check in the RPC library exposes\nkadmind to an integer overflow which can be used to crash kadmind\n(CAN-2003-0028).\n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain backported patches to correct these issues.",

        "text": "Kerberos is a network authentication system. The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped by Red Hat. These vulnerabilities include:\n\nAn integer signedness error in the ASN.1 decoder before version 1.2.5\nallows remote attackers to cause a denial of service (crash) via a large\nunsigned data element length, which is later used as a negative value. The\nCommon Vulnerabilities and Exposures project has assigned the name\nCAN-2002-0036 to this issue. \n\nThe Key Distribution Center (KDC) before version 1.2.5 allows remote,\nauthenticated attackers to cause a denial of service (crash) on KDCs within\nthe same realm using a certain protocol request that causes a null\ndereference (CAN-2003-0058). \n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers to\ncause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes an out-of-bounds read of an array\n(CAN-2003-0072).\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers\nto cause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes the KDC to corrupt its heap\n(CAN-2003-0082).\n\nA vulnerability in Kerberos before version 1.2.3 allows users from one\nrealm to impersonate users in other realms that have the same inter-realm\nkeys (CAN-2003-0059). \n\nThe MIT advisory for these issues also mentions format string\nvulnerabilities in the logging routines (CAN-2003-0060). Previous versions\nof the kerberos packages from Red Hat already contain fixes for this issue.\n\nVulnerabilities have been found in the support for triple-DES keys in the\nimplementation of the Kerberos IV authentication protocol, which is\nincluded in MIT Kerberos (CAN-2003-0139).\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nthat allow an attacker with knowledge of a cross-realm key, which is\nshared with another realm, to impersonate any principal in that realm to\nany service in that realm. This vulnerability can only be closed by\ndisabling cross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5. A faulty length check in the RPC library exposes\nkadmind to an integer overflow, which can be used to crash kadmind\n(CAN-2003-0028).\n\nThe Kerberos 5 network authentication system contains an RPC library which\nincludes an XDR decoder derived from Sun\u0027s RPC implementation. The Sun\nimplementation was recently demonstrated to be vulnerable to a heap\noverflow. It is believed that the attacker needs to be able to\nauthenticate to the kadmin daemon for this attack to be successful\n(CVE-2002-0391).\n\nA stack buffer overflow was found in the implementation of the Kerberos v4\ncompatibility administration daemon (kadmind4), which is part of the the\nMIT krb5 distribution, but not enabled or used by default in Red Hat Linux.\nThis vulnerability could be exploited to gain unauthorized root access to a\nKDC host. The attacker does not need to authenticate to the daemon to\nsuccessfully perform this attack (CAN-2002-1235).\n\nA problem has been found in the Kerberos ftp client. When retrieving a\nfile with a filename beginning with a pipe character, the ftp client will\npass the filename to the command shell in a system() call. This could\nallow a malicious ftp server to write to files outside of the current\ndirectory or execute commands as the user running the ftp client\n(CAN-2003-0041).\n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain backported patches that correct these issues.",

        "text": "Kerberos is a network authentication system. The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped by Red Hat. These vulnerabilities include:\n\nAn integer signedness error in the ASN.1 decoder before version 1.2.5\nallows remote attackers to cause a denial of service (crash) via a large\nunsigned data element length, which is later used as a negative value. The\nCommon Vulnerabilities and Exposures project has assigned the name\nCAN-2002-0036 to this issue. Red Hat Linux 8.0 and later are not affected\nby this issue.\n\nThe Key Distribution Center (KDC) before version 1.2.5 allows remote,\nauthenticated attackers to cause a denial of service (crash) on KDCs within\nthe same realm using a certain protocol request that causes a null\ndereference (CAN-2003-0058). Red Hat Linux 8.0 and later are not affected\nby this issue.\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers to\ncause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes an out-of-bounds read of an array\n(CAN-2003-0072).\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers\nto cause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes the KDC to corrupt its heap\n(CAN-2003-0082).\n\nA vulnerability in Kerberos before version 1.2.3 allows users from one\nrealm to impersonate users in other realms that have the same inter-realm\nkeys (CAN-2003-0059). Red Hat Linux 7.3 and later are not affected by this\nissue.\n\nThe MIT advisory for these issues also mentions format string\nvulnerabilities in the logging routines (CAN-2003-0060). Previous versions\nof the kerberos packages from Red Hat already contain fixes for this issue.\n\nVulnerabilities have been found in the support for triple-DES keys in the\nimplementation of the Kerberos IV authentication protocol which is included\nin MIT Kerberos (CAN-2003-0139).\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nwhich allow an attacker with knowledge of a cross-realm key, which is\nshared with another realm, to impersonate any principal in that realm to\nany service in that realm. This vulnerability can only be closed by\ndisabling cross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5. A faulty length check in the RPC library exposes\nkadmind to an integer overflow which can be used to crash kadmind\n(CAN-2003-0028).\n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain backported patches that correct these issues.",

The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped by Red Hat.\n\nAn integer signedness error in the ASN.1 decoder before version 1.2.5\nallows remote attackers to cause a denial of service via a large unsigned\ndata element length, which is later used as a negative value.  The Common\nVulnerabilities and Exposures project has assigned the name CAN-2002-0036\nto this issue.  \n\nThe Key Distribution Center (KDC) before version 1.2.5 allows remote,\nauthenticated, attackers to cause a denial of service (crash) on KDCs\nwithin the same realm via a certain protocol request that:\n\n- causes a null pointer dereference (CAN-2003-0058).\n\n- causes the KDC to corrupt its heap (CAN-2003-0082).\n\nA vulnerability in Kerberos before version 1.2.3 allows users from\none realm to impersonate users in other realms that have the same\ninter-realm keys (CAN-2003-0059).\n\nThe MIT advisory for these issues also mentions format string\nvulnerabilities in the logging routines (CAN-2003-0060).  Previous versions\nof the kerberos packages from Red Hat already contain fixes for this issue.\n\nVulnerabilities have been found in the implementation of support for\ntriple-DES keys in the implementation of the Kerberos IV authentication\nprotocol included in MIT Kerberos (CAN-2003-0139).\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nwhich allow an attacker with knowledge of a cross-realm key that is shared\nwith another realm to impersonate any principal in that realm to any\nservice in that realm.  This vulnerability can only be closed by disabling\ncross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5.  A faulty length check in the RPC library exposes\nkadmind to an integer overflow which can be used to crash kadmind\n(CAN-2003-0028).\n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain backported patches to correct these issues.",

Depending upon the application, this vulnerability\ncould cause buffer overflows and may be exploitable, leading to arbitrary\ncode execution.\n\nRed Hat would like to thank eEye Digital Security for alerting us to this\nissue.\n\nAn error in the calculation of memory needed for unpacking arrays in the\nXDR decoder in glibc 2.2.5 and earlier can result in a heap buffer\noverflow. Depending upon the application, this vulnerability may be\nexploitable and lead to arbitrary code execution.\n\nA read buffer overflow vulnerability exists in the glibc resolver code in\nversions of glibc up to and including 2.2.5. The vulnerability is triggered\nby DNS packets larger than 1024 bytes and can cause applications to crash.\n\nA buffer overflow vulnerability has been found in the way the glibc\nresolver handles the resolution of network names and addresses via DNS (as\nper Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are\naffected. A system would be vulnerable to this issue if the \"networks\"\ndatabase in /etc/nsswitch.conf includes the \"dns\" entry. By default, Red\nHat Linux ships with \"networks\" set to \"files\" and is therefore not\nvulnerable to this issue. (CAN-2002-0684)\n\nAll users should upgrade to these errata packages, which contain patches to\nthe glibc libraries and are therefore not vulnerable to these issues.\n\nNOTE: Once the glibc upgrade has been completed, you must either reboot the\nsystem or restart all programs on the system (for example, by using telinit\n1 and then switching back to the original runlevel). Rebooting the system\nor restarting the system programs is necessary to avoid vulnerable glibc\ncopies in memory.  In addition, one cannot mix old NSS modules or libresolv\nwith upgraded NSS modules or libresolve in one running application.\n\nNote also that, if sshd is running so that the other services can be\nrestarted remotely or for a remote reboot during an unattended glibc\nupgrade, glibc will also restart sshd.",

The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped as part of Red Hat Linux 9. These issues include:\n\nVulnerabilities have been found in the triple-DES key support found in the\nimplementation of the Kerberos IV authentication protocol included in MIT\nKerberos. The Common Vulnerabilities and Exposures project has assigned\nthe name CAN-2003-0139 to this issue.\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nwhich allow an attacker with knowledge of a cross-realm key, which is\nshared with another realm, to impersonate any principal in that realm to\nany service in that realm. This vulnerability can only be closed by\ndisabling cross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5. A faulty length check in the RPC library exposes\nkadmind to an integer overflow which can be used to crash kadmind\n(CAN-2003-0028).\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers\nto cause a denial of service (crash) on KDCs within the same realm via a\ncertain protocol request that causes the KDC to corrupt its heap\n(CAN-2003-0082).  \n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain patches that correct these issues.",

Sun RPC is a remote procedure call\nframework that allows clients to invoke procedures in a server process\nover a network.  XDR is a mechanism for encoding data structures for use\nwith RPC.  Glibc contains an XDR encoder/decoder derived from Sun\u0027s RPC\nimplementation, which was demonstrated to be vulnerable to an integer\noverflow.\n\nAn integer overflow is present in the xdrmem_getbytes() function of glibc\n2.3.1 and earlier.  Depending upon the application, this vulnerability\ncould cause buffer overflows and may be exploitable leading to arbitrary\ncode execution.\n\nAll users should upgrade to these errata packages which contain patches to\nthe glibc libraries and therefore are not vulnerable to these issues.\n\nRed Hat would like to thank eEye Digital Security for alerting us to this\nissue.\n\nThe Red Hat Linux 8.0 errata packages also contain a number of bug fixes\nthat are not security related. For details, see the list of bugzilla bugs\nfixed by this errata or the ChangeLog.\n\n[Updated 9 April 2003]\nSome bugs newly introduced by the Red Hat Linux 8.0 errata packages\nhas been discovered, such as wine problems or problems with debugging\nthreaded applications.\n\nOnce the glibc upgrade has been completed, you must either reboot the\nsystem or restart all programs on the system (for example, by using telinit\n1 and switching back to the old runlevel). Rebooting the system or\nrestarting the system programs is necessary to avoid vulnerable glibc\ncopies in memory and because changes in NSS internal interfaces which mean\nthat one cannot mix old NSS modules or libresolv in an application with\nupgraded NSS modules or libresolv in one running application.\n\nIf sshd is running so that the other services can be restarted remotely or\nfor a remote reboot during an unattended glibc upgrade, glibc will also\nrestart sshd.",

        "category": "general",
        "text": "Kerberos is a network authentication system. The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped by Red Hat. These vulnerabilities include:\n\nAn integer signedness error in the ASN.1 decoder before version 1.2.5\nallows remote attackers to cause a denial of service (crash) via a large\nunsigned data element length, which is later used as a negative value. The\nCommon Vulnerabilities and Exposures project has assigned the name\nCAN-2002-0036 to this issue. \n\nThe Key Distribution Center (KDC) before version 1.2.5 allows remote,\nauthenticated attackers to cause a denial of service (crash) on KDCs within\nthe same realm using a certain protocol request that causes a null\ndereference (CAN-2003-0058). \n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers to\ncause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes an out-of-bounds read of an array\n(CAN-2003-0072).\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers\nto cause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes the KDC to corrupt its heap\n(CAN-2003-0082).\n\nA vulnerability in Kerberos before version 1.2.3 allows users from one\nrealm to impersonate users in other realms that have the same inter-realm\nkeys (CAN-2003-0059). \n\nThe MIT advisory for these issues also mentions format string\nvulnerabilities in the logging routines (CAN-2003-0060). Previous versions\nof the kerberos packages from Red Hat already contain fixes for this issue.\n\nVulnerabilities have been found in the support for triple-DES keys in the\nimplementation of the Kerberos IV authentication protocol, which is\nincluded in MIT Kerberos (CAN-2003-0139).\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nthat allow an attacker with knowledge of a cross-realm key, which is\nshared with another realm, to impersonate any principal in that realm to\nany service in that realm. This vulnerability can only be closed by\ndisabling cross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5. A faulty length check in the RPC library exposes\nkadmind to an integer overflow, which can be used to crash kadmind\n(CAN-2003-0028).\n\nThe Kerberos 5 network authentication system contains an RPC library which\nincludes an XDR decoder derived from Sun\u0027s RPC implementation. The Sun\nimplementation was recently demonstrated to be vulnerable to a heap\noverflow. It is believed that the attacker needs to be able to\nauthenticate to the kadmin daemon for this attack to be successful\n(CVE-2002-0391).\n\nA stack buffer overflow was found in the implementation of the Kerberos v4\ncompatibility administration daemon (kadmind4), which is part of the the\nMIT krb5 distribution, but not enabled or used by default in Red Hat Linux.\nThis vulnerability could be exploited to gain unauthorized root access to a\nKDC host. The attacker does not need to authenticate to the daemon to\nsuccessfully perform this attack (CAN-2002-1235).\n\nA problem has been found in the Kerberos ftp client. When retrieving a\nfile with a filename beginning with a pipe character, the ftp client will\npass the filename to the command shell in a system() call. This could\nallow a malicious ftp server to write to files outside of the current\ndirectory or execute commands as the user running the ftp client\n(CAN-2003-0041).\n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain backported patches that correct these issues.",

        "text": "Kerberos is a network authentication system. The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped by Red Hat. These vulnerabilities include:\n\nAn integer signedness error in the ASN.1 decoder before version 1.2.5\nallows remote attackers to cause a denial of service (crash) via a large\nunsigned data element length, which is later used as a negative value. The\nCommon Vulnerabilities and Exposures project has assigned the name\nCAN-2002-0036 to this issue. Red Hat Linux 8.0 and later are not affected\nby this issue.\n\nThe Key Distribution Center (KDC) before version 1.2.5 allows remote,\nauthenticated attackers to cause a denial of service (crash) on KDCs within\nthe same realm using a certain protocol request that causes a null\ndereference (CAN-2003-0058). Red Hat Linux 8.0 and later are not affected\nby this issue.\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers to\ncause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes an out-of-bounds read of an array\n(CAN-2003-0072).\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers\nto cause a denial of service (crash) on KDCs within the same realm using a\ncertain protocol request that causes the KDC to corrupt its heap\n(CAN-2003-0082).\n\nA vulnerability in Kerberos before version 1.2.3 allows users from one\nrealm to impersonate users in other realms that have the same inter-realm\nkeys (CAN-2003-0059). Red Hat Linux 7.3 and later are not affected by this\nissue.\n\nThe MIT advisory for these issues also mentions format string\nvulnerabilities in the logging routines (CAN-2003-0060). Previous versions\nof the kerberos packages from Red Hat already contain fixes for this issue.\n\nVulnerabilities have been found in the support for triple-DES keys in the\nimplementation of the Kerberos IV authentication protocol which is included\nin MIT Kerberos (CAN-2003-0139).\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nwhich allow an attacker with knowledge of a cross-realm key, which is\nshared with another realm, to impersonate any principal in that realm to\nany service in that realm. This vulnerability can only be closed by\ndisabling cross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5. A faulty length check in the RPC library exposes\nkadmind to an integer overflow which can be used to crash kadmind\n(CAN-2003-0028).\n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain backported patches that correct these issues.",

The MIT Kerberos team\nreleased an advisory describing a number of vulnerabilities that affect the\nkerberos packages shipped as part of Red Hat Linux 9. These issues include:\n\nVulnerabilities have been found in the triple-DES key support found in the\nimplementation of the Kerberos IV authentication protocol included in MIT\nKerberos. The Common Vulnerabilities and Exposures project has assigned\nthe name CAN-2003-0139 to this issue.\n\nVulnerabilities have been found in the Kerberos IV authentication protocol\nwhich allow an attacker with knowledge of a cross-realm key, which is\nshared with another realm, to impersonate any principal in that realm to\nany service in that realm. This vulnerability can only be closed by\ndisabling cross-realm authentication in Kerberos IV (CAN-2003-0138).\n\nVulnerabilities have been found in the RPC library used by the kadmin\nservice in Kerberos 5. A faulty length check in the RPC library exposes\nkadmind to an integer overflow which can be used to crash kadmind\n(CAN-2003-0028).\n\nThe Key Distribution Center (KDC) allows remote, authenticated attackers\nto cause a denial of service (crash) on KDCs within the same realm via a\ncertain protocol request that causes the KDC to corrupt its heap\n(CAN-2003-0082).  \n\nAll users of Kerberos are advised to upgrade to these errata packages,\nwhich disable cross-realm authentication by default for Kerberos IV and\nwhich contain patches that correct these issues.",

Depending upon the application, this vulnerability\ncould cause buffer overflows and may be exploitable, leading to arbitrary\ncode execution.\n\nRed Hat would like to thank eEye Digital Security for alerting us to this\nissue.\n\nAn error in the calculation of memory needed for unpacking arrays in the\nXDR decoder in glibc 2.2.5 and earlier can result in a heap buffer\noverflow. Depending upon the application, this vulnerability may be\nexploitable and lead to arbitrary code execution.\n\nA read buffer overflow vulnerability exists in the glibc resolver code in\nversions of glibc up to and including 2.2.5. The vulnerability is triggered\nby DNS packets larger than 1024 bytes and can cause applications to crash.\n\nA buffer overflow vulnerability has been found in the way the glibc\nresolver handles the resolution of network names and addresses via DNS (as\nper Internet RFC 1011). Version 2.2.5 of glibc and earlier versions are\naffected. A system would be vulnerable to this issue if the \"networks\"\ndatabase in /etc/nsswitch.conf includes the \"dns\" entry. By default, Red\nHat Linux ships with \"networks\" set to \"files\" and is therefore not\nvulnerable to this issue. (CAN-2002-0684)\n\nAll users should upgrade to these errata packages, which contain patches to\nthe glibc libraries and are therefore not vulnerable to these issues.\n\nNOTE: Once the glibc upgrade has been completed, you must either reboot the\nsystem or restart all programs on the system (for example, by using telinit\n1 and then switching back to the original runlevel). Rebooting the system\nor restarting the system programs is necessary to avoid vulnerable glibc\ncopies in memory.  In addition, one cannot mix old NSS modules or libresolv\nwith upgraded NSS modules or libresolve in one running application.\n\nNote also that, if sshd is running so that the other services can be\nrestarted remotely or for a remote reboot during an unattended glibc\nupgrade, glibc will also restart sshd.",

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",

NFS, NIS, and many other network services are built upon Sun\nRPC.  The XDR encoder/decoder provided with glibc, derived from Sun\u0027s RPC\nimplementation, was demonstrated to be vulnerable to an integer overflow.\n\nAn integer overflow is present in the xdrmem_getbytes() function of glibc\n2.3.1 and earlier.  Depending upon the application, this vulnerability\ncould cause buffer overflows and may be exploitable, leading to arbitrary\ncode execution.  \n\nAll users should upgrade to these errata packages which contain patches to\nthe glibc libraries and, therefore, are not vulnerable to these issues.\n\nRed Hat would like to thank eEye Digital Security for alerting us to this\nissue.",
