Vulnerability Assessment Details

RHSA-2003-121: sendmail

Vulnerability Assessment Summary
Check for the version of the sendmail packages

Detailed Explanation for this Vulnerability Assessment

Updated Sendmail packages are available to fix a vulnerability that
permits local and possibly remote attackers to gain root rights.

Sendmail is a widely used Mail Transport Agent (MTA) which is included
in all Red Hat Enterprise Linux distributions.

There is a vulnerability in Sendmail versions 8.12.8 and prior. The
address parser performs insufficient bounds checking in certain conditions
due to a char to int conversion, making it possible for a possible hacker to
take control of the application. Although no exploit currently exists,
this issue is probably locally exploitable and may be remotely exploitable.

All users are advised to update to these erratum packages containing a
backported patch which corrects these vulnerabilities.

Red Hat would like to thank Michal Zalewski for finding and reporting this
