Nov 11, 2003, 15:57 (2 Talkback[s])

Red Hat Security Advisory

Synopsis: Updated Ethereal packages fix security issues
Advisory ID: RHSA-2003:323-01
Issue date: 2003-11-10
Updated on: 2003-11-10
Product: Red Hat Linux
Keywords: ethereal SOCKS buffer overflow
Cross references:  
Obsoletes: RHSA-2003:203
CVE Names: CAN-2003-0925 CAN-2003-0926 CAN-2003-0927

1. Topic:

Updated Ethereal packages that fix a number of exploitable security issues are now available.

2. Relevant releases/architectures:

Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386

3. Problem description:

Ethereal is a program for monitoring network traffic.

A number of security issues affect Ethereal. By exploiting these issues, it may be possible to make Ethereal crash or run arbitrary code by injecting a purposefully-malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

A buffer overflow in Ethereal 0.9.15 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a malformed GTP MSISDN string. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0925 to this issue.

Ethereal 0.9.15 and earlier allows remote attackers to cause a denial of service (crash) via certain malformed ISAKMP or MEGACO packets. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0926 to this issue.

A heap-based buffer overflow in Ethereal 0.9.15 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the SOCKS dissector. The Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned the name CAN-2003-0927 to this issue.

Users of Ethereal should update to these erratum packages containing Ethereal version 0.9.16, which is not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.

Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
