TITLE:
libsndfile "flac_buffer_copy()" Buffer Overflow Vulnerability

http://secunia.com/advisories/26921/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
libsndfile 1.x
http://secunia.com/product/15775/

DESCRIPTION:
Robert Buchholz has reported a vulnerability in libsndfile, which
potentially can be exploited by malicious people to compromise an
application using the library.

The vulnerability is caused due to a boundary error within the
"flac_buffer_copy()" function in src/flac.c when handling FLAC files
with variable bitrates. This can be exploited to cause a heap-based
buffer overflow by e.g. tricking a user into playing a specially
crafted FLAC file with an application using the library.

Successful exploitation may allow the execution of arbitrary code.

The vulnerability is reported in version 1.0.17. Other versions may
also be affected.

SOLUTION:
Fixed in the BZR repository.

PROVIDED AND/OR DISCOVERED BY:
Robert Buchholz

CHANGELOG:
2007-09-21: Added CVE reference.
