| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2004:136.
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 CVE-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 CVE-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 CVE-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.
