Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : flac vulnerability (USN-540-1)

Description

Sean de Regge discovered that flac did not properly perform bounds checking in many situations. An attacker could send a specially crafted FLAC audio file and execute arbitrary code as the user or cause a denial of service in flac or applications that link against flac.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
