ethereal - buffer overflows

Several vulnerabilities were discovered upstream in ethereal, a
network traffic analyzer. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CAN-2003-0925
  A buffer overflow allows remote attackers to cause a denial of
  service and possibly execute arbitrary code via a malformed GTP
  MSISDN string.

• CAN-2003-0926
  Via certain malformed ISAKMP or MEGACO packets remote attackers are
  able to cause a denial of service (crash).

• CAN-2003-0927
  A heap-based buffer overflow allows remote attackers to cause a
  denial of service (crash) and possibly execute arbitrary code via
  the SOCKS dissector.

• CAN-2003-1012
  The SMB dissector allows remote attackers to cause a denial of
  service via a malformed SMB packet that triggers a segmentation
  fault during processing of selected packets.

• CAN-2003-1013
  The Q.931 dissector allows remote attackers to cause a denial of
  service (crash) via a malformed Q.931, which triggers a null
  dereference.

For the stable distribution (woody) this problem has been fixed in
version 0.9.4-1woody6.

For the unstable distribution (sid) this problem has been fixed in
version 0.10.0-1.

We recommend that you upgrade your ethereal and tethereal packages.
