Detailsinfo

A vulnerability classified as critical has been found in Digium Asterisk (Communications System). This affects an unknown function of the component Session Initiation Protocol. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. 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. This is going to have an impact on availability. The summary by CVE is:

Asterisk 1.4 before 1.4.1 and 1.2 before 1.2.16 allows remote attackers to cause a denial of service (crash) by sending a Session Initiation Protocol (SIP) packet without a URI and SIP-version header, which results in a NULL pointer dereference.

The bug was discovered 03/03/2007. The weakness was shared 03/04/2007 by Mu Security with Mu Security as confirmed advisory (CERT.org). The advisory is shared at kb.cert.org. This vulnerability is uniquely identified as CVE-2007-1306 since 03/06/2007. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed in ANSI C and been published immediately after the advisory. The exploit is shared for download at packetstormsecurity.org. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 25938 (Debian DSA-1358-1 : asterisk - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 38577 (Asterisk SIP Channel Driver Remote Denial of Service Vulnerability).

Upgrading to version 1.4 eliminates this vulnerability. A possible mitigation has been published 7 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (32830), Exploit-DB (3407), Tenable (25938), SecurityFocus (BID 22838†) and OSVDB (33888†). The entries VDB-36613, VDB-36430, VDB-36429 and VDB-37886 are related to this item. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
