Description

It was discovered that libsndfile did not correctly handle description chunks in CAF audio files. If a user or automated system were tricked into opening a specially crafted CAF audio file, an attacker could execute arbitrary code with the privileges of the user invoking the program.

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.
