RHSA-2004:234 - Security Advisory
Synopsis
ethereal security update
Type/Severity
Security Advisory: Moderate
Topic
Updated Ethereal packages that fix various security vulnerabilities are now
available.
Description
Ethereal is a program for monitoring network traffic.
The MMSE dissector in Ethereal releases 0.10.1 through 0.10.3 contained a
buffer overflow flaw. On a system where Ethereal is running, a remote
attacker could send malicious packets that could cause Ethereal to crash or
execute arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0507 to this issue.
In addition, other flaws in Ethereal prior to 0.10.4 were found that could
cause it to crash in response to carefully crafted SIP (CAN-2004-0504), AIM
(CAN-2004-0505), or SPNEGO (CAN-2004-0506) packets.
Users of Ethereal should upgrade to these updated packages, which contain
backported security patches that correct these issues.
