- Updated Ethereal packages that fix various security vulnerabilities are now
- available.
-
- Ethereal is a program for monitoring network traffic.
-
- Stefan Esser reported that Ethereal versions 0.10.1 and earlier contain
- stack overflows in the IGRP, PGM, Metflow, ISUP, TCAP, or IGAP dissectors.
- On a system where Ethereal is being run 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-2004-0176 to this issue.
-
- Jonathan Heussser discovered that a carefully-crafted RADIUS packet could
- cause a crash. The Common Vulnerabilities and Exposures project
- (cve.mitre.org) has assigned the name CAN-2004-0365 to this issue.
-
- Ethereal 0.8.13 to 0.10.2 allows remote attackers to cause a denial of
- service (crash) via a zero-length Presentation protocol selector. The
- Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
- the name CAN-2004-0367 to this issue.
-
- Users of Ethereal should upgrade to these updated packages, which contain
- a version of Ethereal that is not vulnerable to these issues.
