Security Advisory mc security update

Advisory: RHSA-2004:035-01
Type: Security Advisory
Severity: Important
Issued on: 2004-02-03
Last updated on: 2004-02-03
Affected Products: Red Hat Enterprise Linux AS (v. 2.1)
Red Hat Enterprise Linux WS (v. 2.1)
Red Hat Linux Advanced Workstation 2.1 for the Itanium Processor
CVEs (cve.mitre.org): CVE-2003-1023

Details

Updated mc packages that resolve a buffer overflow vulnerability are now
available.

Midnight Commander is a visual shell much like a file manager.

A buffer overflow has been found in Midnight Commander's virtual filesystem
code. Specifically, a stack-based buffer overflow in vfs_s_resolve_symlink
of vfs/direntry.c allows remote attackers to execute arbitrary code during
symlink conversion.

Users of Midnight Commander should install these updated packages, which
resolve 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.

If up2date fails to connect to Red Hat Network due to SSL Certificate
Errors, you need to install a version of the up2date client with an updated
certificate. The latest version of up2date is available from the Red Hat
FTP site and may also be downloaded directly from the RHN website:
