CVE-2014-1551: Use-after-free vulnerability in the FontTableRec destructor in Mozilla Firefox before 31.0, Firefox ESR 24....

Use-after-free vulnerability in the FontTableRec destructor in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 on Windows allows remote attackers to execute arbitrary code via crafted use of fonts in MathML content, leading to improper handling of a DirectWrite font-face object.

Security readout for executives and security teams

This is an old Windows-specific Mozilla memory safety flaw. A malicious page or message using MathML fonts could trigger a use-after-free and potentially run code in vulnerable Firefox or Thunderbird versions. The main business risk is unmanaged legacy software still present on endpoints. Exposure is most likely on Windows systems running obsolete Firefox, Firefox ESR 24.x, or Thunderbird builds from before the fixed releases. Modern supported Mozilla versions are not indicated as affected in the supplied bundle. Treat this as a legacy exposure cleanup item with high impact if vulnerable software remains. It is not supported as an active emergency by the provided evidence, but remote code execution potential justifies prompt removal or upgrade of old Mozilla versions. Mitigation focus: Upgrade Firefox to 31.0 or later, ESR to 24.7 or later, and Thunderbird to 24.7 or later.; Prefer current supported Mozilla releases over legacy fixed versions.; Remove unsupported Mozilla installations from Windows endpoints..
