ethereal security update
Security Advisory: Moderate
Updated Ethereal packages that fix various security vulnerabilities are now
available.
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.
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
