(RHSA-2002:291) ethereal security update

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.
