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.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libsndfile < 1.0.17-r1 >= 1.0.17-r1
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"
