FFmpeg Multiple Vulnerabilities

Multiple vulnerabilities have been identified in FFmpeg, which can be exploited by malicious people to cause a DoS (Denial of Service) and compromise an application using the library.

1. An error in the "tak_decode_frame()" function (libavcodec/takdec.c) can be exploited to cause an out-of-bounds memory access.
2. Some errors related to certain decoding structure (libavcodec/wmalosslessdec.c) can be exploited to cause memory corruptions.
3. An error in the "msrle_decode_frame()" function (libavcodec/msrle.c) can be exploited to cause an out-of-bounds memory access.

Successful exploitation of vulnerability #2 may allow execution of arbitrary code.
