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

Summary

An application using libsndfile could be made to crash or possibly run

programs as your login if it opened a specially crafted file.

Software Description:

- 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.
