Type:	Security Advisory
Severity:	N/A
Issued on:	2003-01-03
Last updated on:	2002-12-17
Affected Products:	Red Hat Linux 6.2 Red Hat Linux 7.0 Red Hat Linux 7.1 Red Hat Linux 7.2 Red Hat Linux 7.3 Red Hat Linux 8.0
OVAL:	N/A
CVEs (cve.mitre.org):	CVE-2002-1365

Details

Updated Fetchmail packages are available for Red Hat Linux versions 6.2, 7,
7.1, 7.2, 7.3, and 8.0 which close a remotely-exploitable vulnerability in
unpatched versions of Fetchmail prior to 6.2.0.

Fetchmail is a remote mail retrieval and forwarding utility intended for
use over on-demand TCP/IP links such as SLIP and PPP connections. A bug
has been found in the header parsing code in versions of Fetchmail prior
to 6.2.0.

This bug allows a remote attacker to crash Fetchmail and potentially
execute arbitrary code by sending a carefully crafted email which is
then parsed by Fetchmail.

All users of Fetchmail are advised to upgrade to the errata packages
containing a backported fix which corrects 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.
