Debian DSA-407-1 : ethereal - buffer overflows

high Nessus Plugin ID 15244

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the ethereal and tethereal packages.

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