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"
