A vulnerability, which was classified as problematic, was found in libav up to 12.3. This affects the function ffseekframebinary of the file /libavformat/utils.c of the component MPEG File Parser. The manipulation leads to null pointer dereference. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used. The bug was initially reported by the researcher to the wrong project. This vulnerability only affects products that are no longer supported by the maintainer.
