Title: Ethereal Q.931 Protocol Dissector Denial of Service Vulnerability
Severity: HIGH
Description:
Ethereal Q.931 protocol dissector is prone to remotely exploitable denial of service vulnerability. This issue has been addressed with the release of Ethereal 0.10.0.
It has been reported that when reading a malformed packet the Q.931 dissector dereferences a null pointer.
The issue may be exploited by causing Ethereal to process a malformed packet. Successful exploitation will cause a denial of service condition in the Ethereal application. Although unconfirmed, this issue may allow an attacker to cause a buffer overflow in the application leading to arbitrary code execution.
Ethereal versions 0.9.16 and prior have been reported to be prone to this issue. This issue has been reported to affect Tethereal as well.
