PLATFORM: Debian GNU/Linux 4.1 (stable) DAMAGE: May lead to the execution of arbitrary code. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is LOW. May lead to the execution of arbitrary code. ASSESSMENT: ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/s-104.shtml ORIGINAL BULLETIN: http://www.debian.org/security/2007/dsa-1442 CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2007-4974 ______________________________________________________________________________ [***** Start Debian Security Advisory DSA-1442-1 *****] Debian Security Advisory DSA-1442-1 libsndfile -- buffer overflow Date Reported: 29 Dec 2007 Affected Packages: libsndfile Vulnerable: Yes Security database references: In Mitre's CVE dictionary: CVE-2007-4974. More information: Rubert Buchholz discovered that libsndfile, a library for reading / writing audio files performs insufficient boundary checks when processing FLAC files, which might lead to the execution of arbitrary code. The old stable distribution (sarge) is not affected by this problem. For the stable distribution (etch), this problem has been fixed in version 1.0.16-2. We recommend that you upgrade your libsndfile packages.
