A vulnerability has been discovered in FFmpeg, which can be exploited by malicious people to compromise an application using the library.
The vulnerability is caused due to an integer overflow error within the "vmd_read_header()" function in libavformat/sierravmd.c. This can be exploited to cause a heap-based buffer overflow via a specially crafted VMD file.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is confirmed in version 0.5. Other versions may also be affected.
