Synopsis

========

 

Multiple heap-based buffer overflow vulnerabilities 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

-------------------------------------------------------------------

1 media-libs/libsndfile < 1.0.20 >= 1.0.20

 

Description

===========

 

The following vulnerabilities have been found in libsndfile:

 

* Tobias Klein reported that the header_read() function in

src/common.c uses user input for calculating a buffer size, possibly

leading to a heap-based buffer overflow (CVE-2009-1788).

 

* The vendor reported a boundary error in the aiff_read_header()

function in src/aiff.c, possibly leading to a heap-based buffer

overflow (CVE-2009-1791).

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted AIFF

or VOC file in a program using libsndfile, possibly resulting in the

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-1.0.20"
