RHSA-2002-170: ethereal Vulnerability Scan


Vulnerability Scan Summary
Check for the version of the ethereal packages

Detailed Explanation for this Vulnerability Test


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 allows 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 allows 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 allows 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 allows
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 allows 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 allows
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.
