Gentoo Linux Security Advisory

Title: libsndfile: Arbitrary code execution (GLSA 201312-14)
Severity: normal
Exploitable: remote
Date: December 17, 2013
Bug(s): #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: media-libs/libsndfile
Vulnerable: < 1.0.25
Unaffected: >= 1.0.25
Architectures: 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:
Code:
# 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.
