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.

Security readout for executives and security teams

CVE-2011-0433 is an old document-parsing memory corruption flaw. A crafted DVI file containing an Adobe Font Metrics file could crash affected software and may allow code execution. The main concern is legacy Linux document viewers or TeX-related tooling that still process untrusted DVI/AFM content. Exposure is most likely in legacy desktop, server, or batch document-processing environments using t1lib, teTeX 3.0.x, Evince, or downstream packages from affected distributions. Modern exposure depends on whether those components remain installed and reachable by untrusted document workflows. Prioritize remediation where document viewers or conversion services handle files from customers, email, uploads, or the internet. For isolated legacy systems without untrusted document input, urgency is lower but modernization should be planned because the affected software is old. Mitigation focus: Apply relevant vendor or distribution security updates for t1lib and affected document packages.; Remove or disable legacy DVI and AFM processing where it is not business-required.; Open untrusted DVI files only in isolated, sandboxed environments..
