Detailsinfo

A vulnerability, which was classified as problematic, was found in Wireshark up to 1.4.11 (Packet Analyzer Software). This affects an unknown code block of the component ANSI A Dissector. The manipulation as part of a Malformed Packet 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:

epan/dissectors/packet-ansi_a.c in the ANSI A dissector in Wireshark 1.4.x before 1.4.12 and 1.6.x before 1.6.6 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a malformed packet.

The weakness was shared 03/27/2012 (Website). The advisory is shared at wireshark.org. This vulnerability is uniquely identified as CVE-2012-1593 since 03/12/2012. It is possible to initiate the attack remotely. The requirement for exploitation is a authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Wireshark and been published 4 weeks after the advisory. The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 74610 (openSUSE Security Update : wireshark (openSUSE-SU-2012:0558-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 120904 (Solaris 11 Support Repository Update (SRU) 8.5 Missing).
