RHSA-2005:687 - Security Advisory

Topic

Updated Ethereal packages that fix various security vulnerabilities are now
available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

The ethereal package is a program for monitoring network traffic.

A number of security flaws have been discovered in Ethereal. On a system
where Ethereal is running, a remote attacker could send malicious packets
to trigger these flaws and cause Ethereal to crash or potentially execute
arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the names CAN-2005-2360, CAN-2005-2361,
CAN-2005-2362, CAN-2005-2363, CAN-2005-2364, CAN-2005-2365, CAN-2005-2366,
and CAN-2005-2367 to these issues.

Users of ethereal should upgrade to these updated packages, which contain
version 0.10.12 which is not vulnerable to these issues.

Note: To reduce the risk of future vulnerabilities in Ethereal, the
ethereal and tethereal programs in this update have been compiled as
Position Independant Executables (PIE) for Red Hat Enterprise Linux 3 and
4. In addition FORTIFY_SOURCE has been enabled for Red Hat Enterprise
Linux 4 packages to provide compile time and runtime buffer checks.
