CVE-2015-4475: The mozilla::AudioSink function in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 mishandles...

The mozilla::AudioSink function in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 mishandles inconsistent sample formats within MP3 audio data, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via a malformed file.

Security readout for executives and security teams

A malformed MP3 file could make vulnerable Firefox versions crash or potentially run attacker-controlled code. The business concern is mainly legacy desktops, kiosks, or packaged Linux environments still using Firefox before 40.0 or Firefox ESR before 38.2. Exposure is most likely on unmanaged or legacy endpoints running obsolete Firefox, Firefox ESR, or distribution-packaged Mozilla builds from 2015-era Linux repositories. Current supported Firefox versions should not be affected based on the stated fixed versions. Treat as high priority only where obsolete Firefox remains in use. For modern managed fleets, this is mainly a hygiene and legacy-discovery issue rather than an emergency response item. Mitigation focus: Upgrade Firefox to 40.0 or later, or Firefox ESR to 38.2 or later.; Apply relevant vendor packages from Mozilla, Ubuntu, Red Hat, SUSE, Gentoo, or Oracle guidance.; Remove unsupported Firefox or ESR builds from managed endpoints..
