Microsoft PowerPoint 2003 PPT Document null pointer dereference

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as critical has been found in Microsoft PowerPoint 2003 (Presentation Software). Affected is some unknown processing of the component PPT Document Handler. 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. CVE summarizes:

PowerPoint in Microsoft Office 2003 does not properly handle a container object whose position value exceeds the record length, which allows user-assisted attackers to cause a denial of service (NULL dereference and application crash) via a crafted PowerPoint (.PPT) file, as demonstrated by Nanika.ppt, and a different vulnerability than CVE-2006-3435, CVE-2006-3876, CVE-2006-3877, and CVE-2006-4694. NOTE: the impact of this issue was originally claimed to be arbitrary code execution, but later analysis demonstrated that this was erroneous.

The weakness was published 10/13/2006 by nanika as MSRC/ARC (Website). The advisory is available at blogs.technet.com. This vulnerability is traded as CVE-2006-5296 since 10/16/2006. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. Technical details are unknown but a public exploit is available.

After even before and not, there has been an exploit disclosed. The exploit is shared for download at exploit-db.com. 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 $5k-$25k. The commercial vulnerability scanner Qualys is able to test this issue with plugin 110047 (Microsoft PowerPoint Buffer Overflow Vulnerability).
