        "text": "[Update 20 Mar 2002:\nAdded kernel packages for Red Hat Linux 6.2 on sparc64.  Updated VNC\npackages as the previous fix caused another denial of service\nvulnerability; thanks to Const Kaplinsky for reporting this]\n\n[Update 14 Mar 2002: \nUpdated kernel packages for Red Hat Linux 6.2 and 7.0 which were missing \nthe zlib fix; added missing kernel-headers package for 6.2.]\n \nThe zlib library provides in-memory compression/decompression \nfunctions. The library is widely used throughout Linux and other \noperating \nsystems. \n \nWhile performing tests on the gdk-pixbuf library, Matthias Clasen created \nan invalid PNG image that caused libpng to crash. Upon further \ninvestigation, this turned out to be a bug in zlib 1.1.3 where certain \ntypes of input will cause zlib to free the same area of memory twice \n(called a \"double free\"). \n \nThis bug can be used to crash any program that takes untrusted \ncompressed input. Web browsers or email programs that \ndisplay image attachments or other programs that uncompress data are \nparticularly affected. This vulnerability makes it easy to perform \nvarious \ndenial-of-service attacks against such programs.  \n \nIt is also possible that an attacker could manage a more significant \nexploit, since the result of a double free is the corruption of the \nmalloc() implementation\u0027s data structures. This could include running \narbitrary code on local or remote systems. \n \nMost packages in Red Hat Linux use the shared zlib library and can be \nprotected against vulnerability by updating to the errata zlib \npackage. However, we have identified a number of packages in Red Hat \nLinux that either statically link to zlib or contain an internal \nversion of zlib code. \n \nAlthough no exploits for this issue or these packages are currently \nknown to exist, this is a serious vulnerability which could be \nlocally or remotely exploited. All users should upgrade affected packages \nimmediately. \n \nAdditionally, if you have any programs that you have compiled yourself, \nyou should check to see if they use zlib. If they link to the shared \nzlib library then they will not be vulnerable once the shared zlib \nlibrary is updated to the errata package. However, if any programs that \ndecompress arbitrary data statically link to zlib or use their own \nversion \nof the zlib code internally, then they need to be patched or \nrecompiled.",

        "text": "The following details apply to the main Red Hat Linux distribution\nonly. Please see advisory RHSA-2002:027 for Powertools packages.\n\ncvs: cvs is a version control system. The cvs package has been rebuilt to\nlink against the shared system zlib instead of the internal version. \n\nAdditionally, cvs has been updated to version 1.11.1p1 for Red Hat Linux\n6.2, 7.0 and 7.1 which also corrects a possible security vulnerability due\nto an improperly initialized global variable. (CAN-2002-0092)\n\ndump: The dump package contains programs for backing up and restoring\nfilesystems.  It links statically to zlib and has been rebuilt\nagainst the errata zlib package.  Red Hat Linux 7, 7.1, and 7.2\npackages have also been upgraded to dump-0.4b25, which includes\nmany non-security fixes.\n\ngcc3: The gcc3 package contains the GNU Compiler Collection version\n3.0. It has been updated to version 3.0.4 and patched to link against\nthe system zlib instead of the internal version.\n\nlibgcj: The libgcj package includes the Java runtime library, which is\nneeded to run Java programs compiled using the gcc Java compiler\n(gcj).  libgcj has been patched to use the shared system zlib.\n\nkernel: The Linux kernel internally contains several variants of zlib \ncode. However, ppp compression is the only implementation that is used with\nuntrusted data streams.  This issue has been patched.  New kernel errata\npackages are included for Red Hat Linux 6.2 and 7.  \n\nUsers of Red Hat Linux 7.1, or 7.2 should update to the currently\nreleased kernel errata RHSA-2002-028 (2.4.9-31) which already contains this\nfix.\n\nNetscape Navigator: Users are advised to obtain an update from Netscape.\n\nrsync: rsync is a program for synchronizing files over a network.\nrsync uses a modified version of zlib internally. These errata\npackages patch this internal version of zlib.\n\nThe rsync update package also fixes another security issue where rsync did\nnot call setgroups() before dropping the privileges of the connecting user.\nHence, it is possible for users to retain the group IDs of any supplemental\ngroups that rsync was started in (for example, supplementary groups of the\nroot user), allowing users to access files they may not otherwise be able\nto access.  Thanks to Martin Pool and Andrew Tridgell for alerting us to\nthis issue. CAN-2002-0080.\n\nVNC: VNC is a remote display system in Powertools 6.2.  VNC has been\npatched to use the system zlib library.  \n\nIn addition, there is a small HTTP server implementation in the VNC server\nwhich can be made to wait indefinitely for input, thereby freezing an\nactive VNC session. The VNC packages recommended by this advisory have\nbeen patched to fix this issue. Users of VNC should be aware that the\nprogram is designed for use on a trusted network.\n\nzlib: The zlib library has been updated with a patch to fix the\naforementioned vulnerability.",

        "text": "[Update 20 Mar 2002:\nAdded kernel packages for Red Hat Linux 6.2 on sparc64.  Updated VNC\npackages as the previous fix caused another denial of service\nvulnerability; thanks to Const Kaplinsky for reporting this]\n\n[Update 14 Mar 2002: \nUpdated kernel packages for Red Hat Linux 6.2 and 7.0 which were missing \nthe zlib fix; added missing kernel-headers package for 6.2.]\n \nThe zlib library provides in-memory compression/decompression \nfunctions. The library is widely used throughout Linux and other \noperating \nsystems. \n \nWhile performing tests on the gdk-pixbuf library, Matthias Clasen created \nan invalid PNG image that caused libpng to crash. Upon further \ninvestigation, this turned out to be a bug in zlib 1.1.3 where certain \ntypes of input will cause zlib to free the same area of memory twice \n(called a \"double free\"). \n \nThis bug can be used to crash any program that takes untrusted \ncompressed input. Web browsers or email programs that \ndisplay image attachments or other programs that uncompress data are \nparticularly affected. This vulnerability makes it easy to perform \nvarious \ndenial-of-service attacks against such programs.  \n \nIt is also possible that an attacker could manage a more significant \nexploit, since the result of a double free is the corruption of the \nmalloc() implementation\u0027s data structures. This could include running \narbitrary code on local or remote systems. \n \nMost packages in Red Hat Linux use the shared zlib library and can be \nprotected against vulnerability by updating to the errata zlib \npackage. However, we have identified a number of packages in Red Hat \nLinux that either statically link to zlib or contain an internal \nversion of zlib code. \n \nAlthough no exploits for this issue or these packages are currently \nknown to exist, this is a serious vulnerability which could be \nlocally or remotely exploited. All users should upgrade affected packages \nimmediately. \n \nAdditionally, if you have any programs that you have compiled yourself, \nyou should check to see if they use zlib. If they link to the shared \nzlib library then they will not be vulnerable once the shared zlib \nlibrary is updated to the errata package. However, if any programs that \ndecompress arbitrary data statically link to zlib or use their own \nversion \nof the zlib code internally, then they need to be patched or \nrecompiled.",

        "text": "The following details apply to the main Red Hat Linux distribution\nonly. Please see advisory RHSA-2002:027 for Powertools packages.\n\ncvs: cvs is a version control system. The cvs package has been rebuilt to\nlink against the shared system zlib instead of the internal version. \n\nAdditionally, cvs has been updated to version 1.11.1p1 for Red Hat Linux\n6.2, 7.0 and 7.1 which also corrects a possible security vulnerability due\nto an improperly initialized global variable. (CAN-2002-0092)\n\ndump: The dump package contains programs for backing up and restoring\nfilesystems.  It links statically to zlib and has been rebuilt\nagainst the errata zlib package.  Red Hat Linux 7, 7.1, and 7.2\npackages have also been upgraded to dump-0.4b25, which includes\nmany non-security fixes.\n\ngcc3: The gcc3 package contains the GNU Compiler Collection version\n3.0. It has been updated to version 3.0.4 and patched to link against\nthe system zlib instead of the internal version.\n\nlibgcj: The libgcj package includes the Java runtime library, which is\nneeded to run Java programs compiled using the gcc Java compiler\n(gcj).  libgcj has been patched to use the shared system zlib.\n\nkernel: The Linux kernel internally contains several variants of zlib \ncode. However, ppp compression is the only implementation that is used with\nuntrusted data streams.  This issue has been patched.  New kernel errata\npackages are included for Red Hat Linux 6.2 and 7.  \n\nUsers of Red Hat Linux 7.1, or 7.2 should update to the currently\nreleased kernel errata RHSA-2002-028 (2.4.9-31) which already contains this\nfix.\n\nNetscape Navigator: Users are advised to obtain an update from Netscape.\n\nrsync: rsync is a program for synchronizing files over a network.\nrsync uses a modified version of zlib internally. These errata\npackages patch this internal version of zlib.\n\nThe rsync update package also fixes another security issue where rsync did\nnot call setgroups() before dropping the privileges of the connecting user.\nHence, it is possible for users to retain the group IDs of any supplemental\ngroups that rsync was started in (for example, supplementary groups of the\nroot user), allowing users to access files they may not otherwise be able\nto access.  Thanks to Martin Pool and Andrew Tridgell for alerting us to\nthis issue. CAN-2002-0080.\n\nVNC: VNC is a remote display system in Powertools 6.2.  VNC has been\npatched to use the system zlib library.  \n\nIn addition, there is a small HTTP server implementation in the VNC server\nwhich can be made to wait indefinitely for input, thereby freezing an\nactive VNC session. The VNC packages recommended by this advisory have\nbeen patched to fix this issue. Users of VNC should be aware that the\nprogram is designed for use on a trusted network.\n\nzlib: The zlib library has been updated with a patch to fix the\naforementioned vulnerability.",

Thanks to Const Kaplinsky for discovering this\nissue.]\n  \nThe zlib compression library provides in-memory compression and  \ndecompression functions. It is widely used throughout Linux  \nand other operating systems.  \n  \nWhile performing tests on the gdk-pixbuf library, Matthias Clasen created  \nan invalid PNG image that caused libpng to crash.  Upon further  \ninvestigation, this turned out to be a bug in zlib 1.1.3. Certain  \ninput will cause zlib to free an area of memory twice (also called a  \n\"double free\").  \n  \nThis bug can be used to crash any program that takes untrusted compressed  \ninput. Web browsers or email programs that display image attachments or  \nother programs that uncompress data are particularly affected. This  \nvulnerability makes it easy to perform various denial-of-service attacks  \nagainst such programs.   \n  \nHowever, since the result of a double free is the corruption of the  \nmalloc implementation\u0027s data structures, it is possible that an attacker\ncould manage a more significant exploit, such as running arbitrary code on\nthe affected system.",

        "text": "Most of the packages in Red Hat Linux use the shared zlib library and can\nbe protected against vulnerability by updating to the errata zlib\npackage.  However, there have been a number of packages identified in Red\nHat Linux that either statically link to zlib or contain an internal\nversion of zlib code.\n\nAlthough no exploits for this issue or the affected packages are currently\nknown to exist, this is a serious vulnerability that could be locally or\nremotely  exploited. All users should upgrade affected packages\nimmediately.\n\nAdditionally, if you have any programs that you have compiled yourself\nyou should check to see if they use zlib. If they link to the shared\nzlib library then they will not be vulnerable once the shared zlib\nlibrary is updated to the errata package. If any programs that decompress\narbitrary data either statically link to zlib or use their own version of\nthe zlib code internally, then they need to be patched or recompiled.\n\nThe following details apply to the Powertools distribution only;\nfor packages included with the main Red Hat Linux distribution\nplease see advisory RHSA-2002:026\n\nabiword: Powertools 6.2 shipped with both statically and\ndynamically linked versions of AbiWord. The statically linked version\nis linked against the vulnerable zlib. It is recommended that users\nonly use the dynamic version.\n\nacroread: The acroread package in Powertools 7.0 contains Acrobat\nReader, a PDF viewer. This package contains an internal version of\nzlib which may be vulnerable. An update is not yet available, so users are\nadvised to view PDF documents using xpdf or ghostview.\n\namaya: Amaya is a Web browser/authoring tool. Amaya in Powertools 7.1\nhas been patched to use the system zlib, libjpeg, and libpng libraries\ninstead of the internal static versions.\n\nflash: The flash package in Powertools 6.2 and 7.0 contains an\nunofficial Shockwave(TM) Flash2/Flash3 plug-in for Netscape which uses\nan internal version of zlib. This plug-in conflicts with the official\nflash plug-in included in the netscape package and should not be used.\n\nfreeamp: Freeamp is an MP3 audio player in Powertools 6.2 and 7.0 which\nuses zlib when decompressing themes. Freeamp has been patched\nto use the system zlib library instead of the internal version.\n\nqt-embedded: Qt is a GUI toolkit for embedded devices.  qt-embedded has\nbeen updated to version 2.3.2 and recompiled against the errata zlib\nlibrary.\n\nvnc: VNC is a remote display system in Powertools 6.2. VNC has been\npatched to use the system zlib library.  \n\nIn addition, there is a small HTTP server implementation in the VNC server\nwhich can be made to wait indefinitely for input, thereby freezing an\nactive VNC session.  The VNC packages recommended by this advisory have\nbeen patched to fix this issue, as well. Users of VNC should be aware  the\nprogram is designed for use on a trusted network.",

However, there have been a number of packages identified in Red\nHat Linux that either statically link to zlib or contain an internal\nversion of zlib code.\n\nAlthough no exploits for this issue or the affected packages are currently\nknown to exist, this is a serious vulnerability that could be locally or\nremotely  exploited. All users should upgrade affected packages\nimmediately.\n\nAdditionally, if you have any programs that you have compiled yourself\nyou should check to see if they use zlib. If they link to the shared\nzlib library then they will not be vulnerable once the shared zlib\nlibrary is updated to the errata package. If any programs that decompress\narbitrary data either statically link to zlib or use their own version of\nthe zlib code internally, then they need to be patched or recompiled.\n\nThe following details apply to the Powertools distribution only;\nfor packages included with the main Red Hat Linux distribution\nplease see advisory RHSA-2002:026\n\nabiword: Powertools 6.2 shipped with both statically and\ndynamically linked versions of AbiWord. The statically linked version\nis linked against the vulnerable zlib. It is recommended that users\nonly use the dynamic version.\n\nacroread: The acroread package in Powertools 7.0 contains Acrobat\nReader, a PDF viewer. This package contains an internal version of\nzlib which may be vulnerable. An update is not yet available, so users are\nadvised to view PDF documents using xpdf or ghostview.\n\namaya: Amaya is a Web browser/authoring tool. Amaya in Powertools 7.1\nhas been patched to use the system zlib, libjpeg, and libpng libraries\ninstead of the internal static versions.\n\nflash: The flash package in Powertools 6.2 and 7.0 contains an\nunofficial Shockwave(TM) Flash2/Flash3 plug-in for Netscape which uses\nan internal version of zlib. This plug-in conflicts with the official\nflash plug-in included in the netscape package and should not be used.\n\nfreeamp: Freeamp is an MP3 audio player in Powertools 6.2 and 7.0 which\nuses zlib when decompressing themes. Freeamp has been patched\nto use the system zlib library instead of the internal version.\n\nqt-embedded: Qt is a GUI toolkit for embedded devices.  qt-embedded has\nbeen updated to version 2.3.2 and recompiled against the errata zlib\nlibrary.\n\nvnc: VNC is a remote display system in Powertools 6.2. VNC has been\npatched to use the system zlib library.  \n\nIn addition, there is a small HTTP server implementation in the VNC server\nwhich can be made to wait indefinitely for input, thereby freezing an\nactive VNC session.  The VNC packages recommended by this advisory have\nbeen patched to fix this issue, as well. Users of VNC should be aware  the\nprogram is designed for use on a trusted network.",

However, ppp compression is the only implementation that is used with\nuntrusted data streams.  This issue has been patched.  New kernel errata\npackages are included for Red Hat Linux 6.2 and 7.  \n\nUsers of Red Hat Linux 7.1, or 7.2 should update to the currently\nreleased kernel errata RHSA-2002-028 (2.4.9-31) which already contains this\nfix.\n\nNetscape Navigator: Users are advised to obtain an update from Netscape.\n\nrsync: rsync is a program for synchronizing files over a network.\nrsync uses a modified version of zlib internally. These errata\npackages patch this internal version of zlib.\n\nThe rsync update package also fixes another security issue where rsync did\nnot call setgroups() before dropping the privileges of the connecting user.\nHence, it is possible for users to retain the group IDs of any supplemental\ngroups that rsync was started in (for example, supplementary groups of the\nroot user), allowing users to access files they may not otherwise be able\nto access.  Thanks to Martin Pool and Andrew Tridgell for alerting us to\nthis issue. CAN-2002-0080.\n\nVNC: VNC is a remote display system in Powertools 6.2.  VNC has been\npatched to use the system zlib library.  \n\nIn addition, there is a small HTTP server implementation in the VNC server\nwhich can be made to wait indefinitely for input, thereby freezing an\nactive VNC session. The VNC packages recommended by this advisory have\nbeen patched to fix this issue. Users of VNC should be aware that the\nprogram is designed for use on a trusted network.\n\nzlib: The zlib library has been updated with a patch to fix the\naforementioned vulnerability.",

        "text": "[Update 20 Mar 2002:\nVNC packages updated to fix another denial of service vulnerability caused\nby the previous update. Thanks to Const Kaplinsky for discovering this\nissue.]\n  \nThe zlib compression library provides in-memory compression and  \ndecompression functions. It is widely used throughout Linux  \nand other operating systems.  \n  \nWhile performing tests on the gdk-pixbuf library, Matthias Clasen created  \nan invalid PNG image that caused libpng to crash.  Upon further  \ninvestigation, this turned out to be a bug in zlib 1.1.3. Certain  \ninput will cause zlib to free an area of memory twice (also called a  \n\"double free\").  \n  \nThis bug can be used to crash any program that takes untrusted compressed  \ninput. Web browsers or email programs that display image attachments or  \nother programs that uncompress data are particularly affected. This  \nvulnerability makes it easy to perform various denial-of-service attacks  \nagainst such programs.   \n  \nHowever, since the result of a double free is the corruption of the  \nmalloc implementation\u0027s data structures, it is possible that an attacker\ncould manage a more significant exploit, such as running arbitrary code on\nthe affected system.",

        "text": "Most of the packages in Red Hat Linux use the shared zlib library and can\nbe protected against vulnerability by updating to the errata zlib\npackage.  However, there have been a number of packages identified in Red\nHat Linux that either statically link to zlib or contain an internal\nversion of zlib code.\n\nAlthough no exploits for this issue or the affected packages are currently\nknown to exist, this is a serious vulnerability that could be locally or\nremotely  exploited. All users should upgrade affected packages\nimmediately.\n\nAdditionally, if you have any programs that you have compiled yourself\nyou should check to see if they use zlib. If they link to the shared\nzlib library then they will not be vulnerable once the shared zlib\nlibrary is updated to the errata package. If any programs that decompress\narbitrary data either statically link to zlib or use their own version of\nthe zlib code internally, then they need to be patched or recompiled.\n\nThe following details apply to the Powertools distribution only;\nfor packages included with the main Red Hat Linux distribution\nplease see advisory RHSA-2002:026\n\nabiword: Powertools 6.2 shipped with both statically and\ndynamically linked versions of AbiWord. The statically linked version\nis linked against the vulnerable zlib. It is recommended that users\nonly use the dynamic version.\n\nacroread: The acroread package in Powertools 7.0 contains Acrobat\nReader, a PDF viewer. This package contains an internal version of\nzlib which may be vulnerable. An update is not yet available, so users are\nadvised to view PDF documents using xpdf or ghostview.\n\namaya: Amaya is a Web browser/authoring tool. Amaya in Powertools 7.1\nhas been patched to use the system zlib, libjpeg, and libpng libraries\ninstead of the internal static versions.\n\nflash: The flash package in Powertools 6.2 and 7.0 contains an\nunofficial Shockwave(TM) Flash2/Flash3 plug-in for Netscape which uses\nan internal version of zlib. This plug-in conflicts with the official\nflash plug-in included in the netscape package and should not be used.\n\nfreeamp: Freeamp is an MP3 audio player in Powertools 6.2 and 7.0 which\nuses zlib when decompressing themes. Freeamp has been patched\nto use the system zlib library instead of the internal version.\n\nqt-embedded: Qt is a GUI toolkit for embedded devices.  qt-embedded has\nbeen updated to version 2.3.2 and recompiled against the errata zlib\nlibrary.\n\nvnc: VNC is a remote display system in Powertools 6.2. VNC has been\npatched to use the system zlib library.  \n\nIn addition, there is a small HTTP server implementation in the VNC server\nwhich can be made to wait indefinitely for input, thereby freezing an\nactive VNC session.  The VNC packages recommended by this advisory have\nbeen patched to fix this issue, as well. Users of VNC should be aware  the\nprogram is designed for use on a trusted network.",
