Summary
Red Hat Security Advisory: sendmail security update

Notes

Topic
Updated Sendmail packages that fix a potentially-exploitable vulnerability are now available.
Details
Sendmail is a widely used Mail Transport Agent (MTA) and is included in all Red Hat Enterprise Linux distributions. There is a bug in the prescan() function of Sendmail versions prior to and including 8.12.9. The sucessful exploitation of this bug can lead to heap and stack structure overflows. Although no exploit currently exists, this issue is locally exploitable and may also be remotely exploitable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0694 to this issue. 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.

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.\n\nIf up2date fails to connect to Red Hat Network due to SSL Certificate \nErrors, you need to install a version of the up2date client with an updated \ncertificate.  The latest version of up2date is available from the Red Hat \nFTP site and may also be downloaded directly from the RHN website:\n\nhttps://rhn.redhat.com/help/latest-up2date.pxt",
