Multiple vulnerabilities have been reported in FLAC, which can be exploited by malicious people to compromise a user's system.

The vulnerabilities are caused due to various errors e.g. integer overflow errors, double-free errors, and boundary errors in various components when processing FLAC media files and can be exploited to cause heap-based or stack-based buffer overflows via specially-crafted FLAC media files.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are reported in version 1.2.0. Prior versions and other applications using the vulnerable library may also be affected.

Solution
Update to version 1.2.1.
