Advisory: RHSA-2003:121-06
Type: Security Advisory
Severity: Critical
Issued on: 2003-03-31
Last updated on: 2003-03-31
Affected Products: Red Hat Enterprise Linux AS (v. 2.1)
Red Hat Enterprise Linux ES (v. 2.1)
Red Hat Enterprise Linux WS (v. 2.1)

CVEs (cve.mitre.org): CVE-2003-0161

Details

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

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 an attacker 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
issue.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
