TITLE:
xine-lib "rmff_dump_cont()" Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA28384

VERIFY ADVISORY:
http://secunia.com/advisories/28384/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
xine-lib 1.x
http://secunia.com/product/3410/

DESCRIPTION:
Luigi Auriemma has discovered some vulnerabilities in xine-lib, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerabilities are caused due to boundary errors within the
"rmff_dump_cont()" function in input/libreal/rmff.c when processing
the SDP "Title", "Author", Copyright", and "Abstract" attributes.
These can be exploited to cause a heap-based buffer overflow by
tricking the user into connecting to a malicious RTSP server.

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities are confirmed in version 1.1.9. Other versions
may also be affected.

SOLUTION:
Do not connect to untrusted streaming servers.

PROVIDED AND/OR DISCOVERED BY:
Luigi Auriemma. Additional information provided by Secunia Research.
