GLSA 201312-14: libsndfile: Arbitrary code execution

http://security.gentoo.org/

Severity:	normal
Title:	libsndfile: Arbitrary code execution
Date:	12/17/2013
Bugs:	#375125
ID:	201312-14

Synopsis

An integer overflow in libsndfile might allow remote attackers to execute arbitrary code or cause a Denial of Service condition.

Background

Libsndfile is a C library for reading and writing files containing sampled sound through one standard library interface.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/libsndfile	< 1.0.25	>= 1.0.25	All supported architectures

Description

An integer overflow flaw has been discovered in Libsndfile.

Impact

A remote attacker could entice a user to open a specially crafted PAF file using libsndfile, possibly resulting in execution of arbitrary code with the privileges of the process, or a Denial of Service condition.

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-1.0.25"

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

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since September 12, 2011. It is likely that your system is already no longer affected by this issue.
