- 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.
- (CAN-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. (CAN-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 (CAN-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. (CAN-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. (CAN-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).
- (CAN-2002-0404)
-
- Users of Ethereal should update to the errata packages containing Ethereal
- version 0.9.6 which is not vulnerable to these issues.
