Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions FFmpeg versions prior to 3.0

Description An issue was discovered in the FFmpeg package, where the vp3 decode frame function in libavcodec/vp3.c lacks a check of the return value of av malloc(), which will cause a null pointer dereference. This impacts availability and potentially confidentiality. The issue can be exploited by a remote attacker to cause a denial of service.

Recommendations For FFmpeg versions prior to 3.0, consider updating to a version that includes a fix for this issue. As a temporary workaround, consider restricting access to the vp3 decode frame function in libavcodec/vp3.c to minimize the risk of exploitation. Additionally, ensure that error handling for memory allocation is properly implemented to prevent similar issues.
