Vulnerability in GIOP dissector in Ethereal before 0.9.3 allows remote attackers to cause a denial of service (memory consumption).

Ethereal versions prior to 0.9.3 were vulnerable to an allocation error in the ASN.1 parser. This can be triggered when analyzing traffic using the SNMP, LDAP, COPS, or Kerberos protocols in ethereal.
This vulnerability was announced in the ethereal security advisory enpa-sa-00003. This issue has been corrected in ethereal version 0.8.0-3potato for Debian 2.2 (potato).

Additionally, a number of vulnerabilities were discussed in ethereal security advisory enpa-sa-00004; the version of ethereal in Debian 2.2 (potato) is not vulnerable to the issues raised in this later advisory. Users of the not-yet-released woody distribution should ensure that they are running ethereal 0.9.4-1 or a later version.

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.
