Severity:	normal
Title:	libsndfile: User-assisted execution of arbitrary code
Date:	04/17/2009
Bugs:	#261173
ID:	200904-16

Synopsis

A buffer overflow vulnerability in libsndfile might allow remote attackers to execute arbitrary code.

Background

libsndfile is a C library for reading and writing files containing sampled sound.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/libsndfile	< 1.0.19	>= 1.0.19	All supported architectures

Description

Alin Rad Pop from Secunia Research reported an integer overflow when processing CAF description chunks, leading to a heap-based buffer overflow.

Impact

A remote attacker could entice a user to open a specially crafted CAF file, resulting in the remote execution of arbitrary code with the privileges of the user running the application.

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-1.0.19"
