USN-1174-1: libsndfile vulnerability

Publication date

25 July 2011

Overview

An application using libsndfile could be made to crash or possibly run programs as your login if it opened a specially crafted file.

Releases

Packages

  • libsndfile - Library for reading/writing audio files

Details

Hossein Lotfi discovered that libsndfile did not properly verify the header
length and number of channels for PARIS Audio Format (PAF) audio files. An
attacker could exploit this to cause a denial of service via application
crash, or possibly execute arbitrary code with the privileges of the user
invoking the program.
