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 very critical, was found in Red Hat Evince. Affected is an unknown code block of the component Font Parser. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the AFM font parser in the dvi-backend component in Evince 2.32 and earlier, teTeX 3.0, t1lib 5.1.2, and possibly other products allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font in conjunction with a DVI file that is processed by the thumbnailer.

The weakness was released 01/07/2011 by Marc Deslauriers as Bug 666318 as confirmed bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2010-2642 since 07/06/2010. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 10/11/2021).

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 68602 (Oracle Linux 5 : tetex (ELSA-2012-1201)), 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 350707 (Amazon Linux Security Advisory for t1lib: ALAS-2012-040).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at Tenable (68602). Entries connected to this vulnerability are available at 55957, 55955, 55954 and 56981.
