Background
Flac is an open-source audio coding format that provides lossless compression. It is widely used for archiving and distributing high-quality audio files. The parse_options function in the flac package is responsible for parsing command-line options. However, a vulnerability has been discovered in this function that can lead to a heap-use-after-free condition.
Vulnerability Detail
The vulnerability occurs when the parse_options function in flac is called. It results in a heap-use-after-free WRITE 4 crash state. This can be exploited by an attacker to execute arbitrary code or cause a denial-of-service condition. The issue was reported through the OSS-Fuzz project and has been assigned a high severity rating.
