"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 execute 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."
