- Updated Ethereal packages are available which fix various security issues.
-
- [Updated 06 Feb 2003]
- Added fixed packages for Advanced Workstation 2.1
-
- Ethereal is a package designed for monitoring network traffic on your
- system. Several security issues have been found in the Ethereal packages
- distributed with Red Hat Linux Advanced Server 2.1.
-
- Multiple errors involving signed integers in the BGP dissector in Ethereal
- 0.9.7 and earlier allow remote attackers to cause a denial of service
- (infinite loop) via malformed messages. This problem was discovered by
- Silvio Cesare. The Common Vulnerabilities and Exposures project
- (cve.mitre.org) has assigned the name CAN-2002-1355 to this issue.
-
- Ethereal 0.9.7 and earlier allows remote attackers to cause a denial
- of service (crash) and possibly execute arbitrary code via malformed
- packets to the LMP, PPP, or TDS dissectors. The Common Vulnerabilities and
- Exposures project (cve.mitre.org) has assigned the name CAN-2002-1356 to
- this issue.
-
- Users of Ethereal should update to the errata packages containing Ethereal
- version 0.9.8 which is not vulnerable to these issues.
