A vulnerability, which was classified as critical, has been found in t1lib 3.0.x. Affected by this issue is the function linetoken of the file afmparse.c. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the linetoken function in afmparse.c in t1lib, as used in teTeX 3.0.x, GNOME evince, and possibly other products, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a DVI file containing a crafted Adobe Font Metrics (AFM) file, a different vulnerability than CVE-2010-2642.

The weakness was shared 11/19/2012 by Jan Lieskovsky as Bug 679732 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com.
