xine-lib <= 1.1.9 'rmff_dump_cont()' Remote Heap Buffer Overflow Vulnerability

                                                source: http://www.securityfocus.com/bid/27198/info

The xine-lib library is prone to a remote heap-based buffer-overflow vulnerability. This issue occurs because the software fails to perform adequate boundary checks on user-supplied data.

An attacker can exploit this issue to execute arbitrary code with the privileges of the user running the affected application. Failed exploit attempts will result in a denial-of-service condition.

This issue affects xine-lib 1.1.9 and prior versions. 

The following proof-of-concept SDP data is available:

a=Abstract:buffer;'QUFBQUFBQUFBQUFBQUFB...40000_of_QUFBQUFB's...FBQUFB'

When decoding 'QUFBQUFB', the portion will be decoded to 'AAAAAA'.
