Gentoo: GLSA-200711-15: FLAC: Buffer overflow
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200711-15 https://security.gentoo.org/
Severity: Normal Title: FLAC: Buffer overflow Date: November 12, 2007 Bugs: #195700 ID: 200711-15
Synopsis ======= Multiple integer overflow vulnerabilities were found in FLAC possibly allowing for the execution of arbitrary code.
Background ========= The Xiph.org Free Lossless Audio Codec (FLAC) library is the reference implementation of the FLAC audio file format. It contains encoders and decoders in library and executable form.
Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/flac < 1.2.1-r1 >= 1.2.1-r1
========== Sean de Regge reported multiple integer overflows when processing FLAC media files that could lead to improper memory allocations resulting in heap-based buffer overflows.
Impact ===== A remote attacker could entice a user to open a specially crafted FLAC file or network stream with an application using FLAC. 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 FLAC users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/flac-1.2.1-r1"
You should also run revdep-rebuild to rebuild any packages that depend on older versions of FLAC:
# revdep-rebuild --library=libFLAC.*
References ========= [ 1 ] CVE-2007-4619 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4619
