Summary
Gentoo Linux Security Advisory GLSA 200710-04
https://security.gentoo.org/
Severity: Normal
Title: libsndfile: Buffer overflow
Date: October 07, 2007
Bugs: #192834
ID: 200710-04
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
==========
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"
