| Doc Text: |
A flaw was found in FFmpeg. The decompression component in the audio decoder fails to properly validate input codes against internal dictionary boundaries. An attacker could exploit this vulnerability by tricking a user or system into processing a specially crafted MPEG-4 ALS (Audio Lossless Coding) file, causing uninitialized heap memory to be copied into the decoded audio output. This may lead to information disclosure by exposing sensitive data from application memory.
