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 heap read operation and memory corruption) or possibly execute arbitrary code via vectors involving the NPUSHB and NPUSHW instructions in a TrueType font.

Security readout for executives and security teams

This is an old FreeType font-rendering flaw. A malicious TrueType font could crash software using vulnerable FreeType and might allow code execution. Business risk depends on whether legacy systems or bundled applications still use FreeType before 2.4.9 or named affected products such as Firefox Mobile before 10.0.4. Exposure is most likely in legacy Linux or appliance environments, mobile/browser stacks, document viewers, or applications that bundle old FreeType libraries and render untrusted fonts. The bundle names Firefox Mobile before 10.0.4 and references multiple vendor advisories, but does not enumerate all affected downstream products. Prioritize remediation for internet-facing, email/document-processing, browser, or content-rendering systems that still run legacy FreeType. For modern managed endpoints, urgency is lower if vendor patches are already applied. The main executive concern is hidden bundled libraries in older software or appliances. Mitigation focus: Inventory FreeType versions in operating systems, containers, appliances, and bundled application libraries.; Upgrade FreeType to 2.4.9 or later, or install the vendor-patched package.; Update Firefox Mobile to 10.0.4 or later where that product exists..
