RHSA-2002-170: ethereal

Vulnerability Assessment Summary
Check for the version of the ethereal packages

Detailed Explanation for this Vulnerability Assessment

Updated ethereal packages are available which fix several security problems.

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:

Buffer overflow in Ethereal 0.9.5 and earlier permits remote attackers to
cause a denial of service or execute arbitrary code via the ISIS dissector.
(CVE-2002-0834)

Buffer overflows in Ethereal 0.9.4 and earlier permits remote attackers
to cause a denial of service or execute arbitrary code via (1) the BGP
dissector, or (2) the WCP dissector. (CVE-2002-0821)

Ethereal 0.9.4 and earlier permits remote attackers to cause a denial
of service and possibly excecute arbitrary code via the (1) SOCKS, (2)
RSVP, (3) AFS, or (4) LMP dissectors, which can be caused to core
dump (CVE-2002-0822)

A buffer overflow in the X11 dissector in Ethereal before 0.9.4 permits
remote attackers to cause a denial of service (crash) and possibly
execute arbitrary code while Ethereal is parsing keysyms. (CVE-2002-0402)

The DNS dissector in Ethereal before 0.9.4 permits remote attackers to
cause a denial of service (CPU consumption) via a malformed packet
that causes Ethereal to enter an infinite loop. (CVE-2002-0403)

A vulnerability in the GIOP dissector in Ethereal before 0.9.4 permits
remote attackers to cause a denial of service (memory consumption).
(CVE-2002-0404)

Users of Ethereal should update to the errata packages containing Ethereal
version 0.9.6 which is not vulnerable to these issues.
