RHSA-2005:306 - 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.

A buffer overflow flaw was discovered in the Etheric dissector. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0704 to this issue.

The GPRS-LLC dissector could crash if the "ignore cipher bit" option was
set. The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2005-0705 to this issue.

A buffer overflow flaw was discovered in the 3GPP2 A11 dissector. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2005-0699 to this issue.

A buffer overflow flaw was discovered in the IAPP dissector. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0739 to this issue.

Users of ethereal should upgrade to these updated packages, which contain
version 0.10.10 and are not vulnerable to these issues.
