CVE-2011-2696: Buffer Overflow

First published: Thu Jul 14 2011(Updated: )

An integer overflow, leading to heap-based buffer overflow flaw was found in the way libsndfile, library for reading and writing of sound files, processed certain PARIS Audio Format (PAF) audio files with crafted count of channels in the PAF file header. A remote attacker could provided a specially-crafted PAF audio file, which once opened by a local, unsuspecting user in an application, linked against libsndfile could lead to that particular application crash (denial of service), or, potentially arbitrary code execution with the privileges of the user running the application.
