DESCRIPTION:
Hossein Lotfi has discovered two vulnerabilities in VLC Media Player,
which can be exploited by malicious people to compromise a user's
system.

1) An integer overflow error when parsing a RealAudio data block
within RealMedia (RM) files can be exploited to cause a heap-based
buffer overflow.

2) An integer underflow error when parsing the "strf" chunk within
AVI files can be exploited to cause a heap-based buffer overflow.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code.

The vulnerabilities are confirmed in version 1.1.10. Prior versions
may also be affected.

SOLUTION:
Fixed in the GIT repository. Fixes will be available in version
1.1.11.
