Summary
Red Hat Security Advisory: : Updated sendmail packages fix vulnerability
Notes
Topic
Updated Sendmail packages are available to fix a vulnerability that
allows local and possibly remote attackers to gain root privileges.
Details
Sendmail is a widely used Mail Transport Agent (MTA) which is included
in all Red Hat Linux distributions.
There is a vulnerability in Sendmail versions prior to and including
8.12.8. The address parser performs insufficient bounds checking in certain
conditions due to a char to int conversion, making it possible for an
attacker to take control of the application. Although no exploit currently
exists, this issue is probably locally exploitable and may also 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
issue.
