Detailsinfo

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.
