The Q.931 dissector in Ethereal before 0.10.0, and Tethereal, allows remote attackers to cause a denial of service (crash) via a malformed Q.931, which triggers a null dereference.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
