TITLE:
libvorbis Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA30234

VERIFY ADVISORY:
http://secunia.com/advisories/30234/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
libvorbis 1.x
http://secunia.com/product/14933/

DESCRIPTION:
Some vulnerabilities have been reported in libvorbis, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
potentially to compromise an application using the library.

1) An input validation error can be exploited to crash an
application, cause an infinite loop, or to cause a heap overflow via
a specially crafted OGG file containing a codebook dimension of "0".

2) An integer overflow error in the processing of residue partition
values can be exploited to cause a heap-based buffer overflow via a
specially crafted OGG file.

3) An integer overflow error exists in the computation of "quantvals"
and of required space for "quantlist". This can be exploited to cause
a heap-based buffer overflow via a specially crafted OGG file.

Successful exploitation may allow execution of arbitrary code.

SOLUTION:
Fixed in the SVN repository.
