A remote attacker can send a carefully crafted email message\nwhich, when processed by sendmail, causes arbitrary code to be\nexecuted as root.\n\nWe are advised that a proof-of-concept exploit is known to exist, but\nis not believed to be in the wild.\n\nSince this is a message-based vulnerability, MTAs other than Sendmail\nmay pass on the carefully crafted message.  This means that unpatched\nversions of Sendmail inside a network could still be at risk even if\nthey do not accept external connections directly.\n\nIn addition, the restricted shell (SMRSH) in Sendmail  allows attackers to\nbypass the intended restrictions of smrsh by inserting additional commands\nafter \"||\" sequences or \"/\" characters, which are not properly filtered or\nverified.  A sucessful attack would allow an attacker who has a local\naccount on a system which has explicitly enabled smrsh to execute arbitrary\nbinaries as themselves by utilizing their .forward file. \n\nAll users are advised to update to these erratum packages.  For Red Hat\nLinux 8.0 we have included Sendmail version 8.12.8 which is not vulnerable\nto these issues.  For all other distributions we have included a backported\npatch which corrects these vulnerabilities.\n\nRed Hat would like to thank Eric Allman for his assistance with this\nvulnerability.",

A remote attacker can send a carefully crafted email message\nwhich, when processed by sendmail, causes arbitrary code to be\nexecuted as root.\n\nWe are advised that a proof-of-concept exploit is known to exist, but\nis not believed to be in the wild.\n\nSince this is a message-based vulnerability, MTAs other than Sendmail\nmay pass on the carefully crafted message.  This means that unpatched\nversions of Sendmail inside a network could still be at risk even if\nthey do not accept external connections directly.\n\nIn addition, the restricted shell (SMRSH) in Sendmail  allows attackers to\nbypass the intended restrictions of smrsh by inserting additional commands\nafter \"||\" sequences or \"/\" characters, which are not properly filtered or\nverified.  A sucessful attack would allow an attacker who has a local\naccount on a system which has explicitly enabled smrsh to execute arbitrary\nbinaries as themselves by utilizing their .forward file. \n\nAll users are advised to update to these erratum packages.  For Red Hat\nLinux 8.0 we have included Sendmail version 8.12.8 which is not vulnerable\nto these issues.  For all other distributions we have included a backported\npatch which corrects these vulnerabilities.\n\nRed Hat would like to thank Eric Allman for his assistance with this\nvulnerability.",

        "text": "Sendmail is a widely used Mail Transport Agent (MTA).\n\nA vulnerability exists in unpatched Sendmail versions prior to and\nincluding 8.12.8. The address parser performs insufficient bounds checking\nin certain conditions due to a char to int conversion, making it possible\nfor an attacker to take control of the application.  This issue is probably\nlocally exploitable and may also be remotely exploitable.  The Common\nVulnerabilities and Exposures project (cve.mitre.org) has assigned the name\nCAN-2003-0161 to this issue.\n\nDuring a code audit of Sendmail by ISS, a critical vulnerability was\nuncovered that affects unpatched versions of Sendmail prior to version\n8.12.8. A remote attacker can send a carefully crafted email message\nwhich, when processed by Sendmail, causes arbitrary code to be\nexecuted as root. A proof-of-concept exploit is reported to exist, but is\nnot believed to be publicly available.\n\nSince this vulnerability is message-based, MTAs other than Sendmail\nmay pass on the carefully crafted message. This means that unpatched\nversions of Sendmail inside a network could still be at risk even if\nthey do not accept external connections directly.  The Common\nVulnerabilities and Exposures project (cve.mitre.org) has assigned the name\nCAN-2002-1337 to this issue.\n\nIn addition, the restricted shell (SMRSH) in Sendmail allows attackers to\nbypass the intended restrictions of smrsh by inserting additional commands\nafter \"||\" sequences or \"/\" characters, which are not properly filtered or\nverified. A successful attack would allow an attacker who has a local\naccount on a system which has explicitly enabled smrsh to execute arbitrary\nbinaries as themselves by utilizing their .forward file. The Common\nVulnerabilities and Exposures project (cve.mitre.org) has assigned the name\nCAN-2002-1165 to this issue.\n\nAll users are advised to update to these erratum packages containing\nbackported patches which correct these vulnerabilities.",

The Common\nVulnerabilities and Exposures project (cve.mitre.org) has assigned the name\nCAN-2003-0161 to this issue.\n\nDuring a code audit of Sendmail by ISS, a critical vulnerability was\nuncovered that affects unpatched versions of Sendmail prior to version\n8.12.8.

A proof-of-concept exploit is reported to exist, but is\nnot believed to be publicly available.\n\nSince this vulnerability is message-based, MTAs other than Sendmail\nmay pass on the carefully crafted message.
