Detail

Synopsis

A buffer overflow vulnerability has been discovered in libsndfile.

Background

libsndfile is a library for reading and writing various formats of audio files including WAV and FLAC.

Description

Robert Buchholz of the Gentoo Security team discovered that the flac_buffer_copy() function does not correctly handle FLAC streams with variable block sizes which leads to a heap-based buffer overflow
(CVE-2007-4974).

Impact

A remote attacker could exploit this vulnerability by enticing a user to open a specially crafted FLAC file or network stream with an application using libsndfile. This might lead to the execution of arbitrary code with privileges of the user playing the file.

Workaround

There is no known workaround at this time.

Resolution

All libsndfile users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libsndfile-1.0.17-r1"
