Array index error in FreeType before 2.4.9, as used in Mozilla Firefox Mobile before 10.0.4 and other products, allows remote attackers to cause a denial of service (invalid stack read operation and memory corruption) or possibly execute arbitrary code via crafted glyph data in a BDF font.

Security readout for executives and security teams

CVE-2012-1139 is a FreeType font parsing flaw. A specially crafted BDF font could crash software using vulnerable FreeType and may allow code execution. Business risk is concentrated in legacy systems, mobile browsers, operating systems, or products still carrying FreeType before 2.4.9. Likely exposure is old software that parses untrusted fonts with FreeType before 2.4.9, especially legacy Linux distributions, Apple systems, embedded products, and Firefox Mobile before 10.0.4. Modern supported platforms are less likely exposed if vendor security updates were applied. Treat as a legacy exposure issue with serious technical impact. Prioritize remediation where unsupported systems process external fonts or documents. Supported, regularly patched systems should be checked but are less likely to need emergency action. Mitigation focus: Upgrade FreeType to 2.4.9 or a vendor-patched package.; Apply relevant OS or browser security updates from vendors.; Remove or isolate unsupported systems using vulnerable FreeType builds..
