CVE-2011-5244: Multiple off-by-one errors in the (1) token and (2) linetoken functions in backend/dvi/mdvi-lib/afmparse.c...

Multiple off-by-one errors in the (1) token and (2) linetoken functions in backend/dvi/mdvi-lib/afmparse.c in t1lib, as used in teTeX 3.0.x, GNOME evince, and possibly other products, allow 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, different vulnerabilities than CVE-2010-2642 and CVE-2011-0433.

Security readout for executives and security teams

A crafted DVI document containing AFM font data could crash affected document viewers or libraries and may allow code execution. The issue is in t1lib code used by teTeX 3.0.x, GNOME Evince, and possibly other products. Business risk is mainly from opening untrusted DVI or TeX-related files on outdated systems. Most likely exposure is legacy Linux or Unix systems with Evince, teTeX 3.0.x, or products embedding the affected t1lib AFM parser. Modern distributions may already include backported fixes, but package lineage should be verified. Prioritize remediation where legacy document viewers or automated DVI processing touch external files. For ordinary modern desktops, confirm patch status during routine vulnerability management; escalate if unsupported packages remain in use. Mitigation focus: Update Evince, t1lib, teTeX, and related packages through supported vendor channels.; Review GNOME and distribution advisories for fixed package versions and backports.; Restrict handling of untrusted DVI or AFM files on legacy systems..
