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.

A vulnerability, which was classified as critical, was found in pango up to 1.22. Affected is the function pango_glyph_string_set_size of the file pango/glyphstring.c. The manipulation with an unknown input leads to a numeric error vulnerability. CWE is classifying the issue as CWE-189. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Integer overflow in the pango_glyph_string_set_size function in pango/glyphstring.c in Pango before 1.24 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long glyph string that triggers a heap-based buffer overflow, as demonstrated by a long document.location value in Firefox.

The weakness was presented 05/07/2009 by Peter Van der Beken (moz_bug_r_a4) with Martijn Wargers as confirmed advisory (CERT.org). The advisory is shared for download at ocert.org. This vulnerability is traded as CVE-2009-1194 since 03/31/2009. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 67856 (Oracle Linux 3 / 4 / 5 : pango (ELSA-2009-0476)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 116528 (Mozilla Firefox/Thunderbird Multiple Remote Vulnerabilities (MFSA 2009-34, MFSA 2009-35, MFSA 2009-36, MFSA 2009-37, MFSA 2009-39, MFSA 2009-40)).

Upgrading to version 1.2 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 8756.

The vulnerability is also documented in the databases at X-Force (50397) and Tenable (67856). See 49120, 49119, 49118 and 49117 for similar entries.
