TagLib: Multiple vulnerabilities

Background

TagLib is a library for reading and editing audio meta data.

Description

Multiple vulnerabilities have been found in TagLib:

• The “analyzeCurrent()” function in ape/apeproperties.cpp contains a division by zero error (CVE-2012-1107).
• The “parse()” function in inogg/xiphcomment.cpp contains an error when processing the “vendorLength” field (CVE-2012-1108).
• The “mid()” function in toolkit/tbytevector.cpp contains an integer overflow error (CVE-2012-1584).

Impact

A remote attacker could entice a user or automated system to open a specially crafted OGG file with an application using TagLib, possibly resulting in a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All TagLib users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/taglib-1.7.1"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
