RHEL 2.1 / 3 : ethereal (RHSA-2004:002)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated Ethereal packages that fix two security vulnerabilities are
now available.

Ethereal is a program for monitoring network traffic.

Two security issues have been found that affect Ethereal. By
exploiting these issues it may be possible to make Ethereal crash by
injecting an intentionally malformed packet onto the wire or by
convincing someone to read a malformed packet trace file. It is not
known if these issues could allow arbitrary code execution.

The SMB dissector in Ethereal before 0.10.0 allows remote attackers to
cause a denial of service via a malformed SMB packet that triggers a
segmentation fault during processing of Selected packets. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2003-1012 to this issue.

The Q.931 dissector in Ethereal before 0.10.0 allows remote attackers
to cause a denial of service (crash) via a malformed Q.931, which
triggers a null dereference. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2003-1013 to this
issue.

Users of Ethereal should update to these erratum packages containing
Ethereal version 0.10.0, which is not vulnerable to these issues.
