  "details" : [ "When decoding a frame for a SANM file (ANIM v0 variant), the decoded data can be larger than the buffer allocated for it.\nFrames encoded with codec 48 can specify their resolution (width x height). A buffer of appropriate size is allocated depending on the resolution.\nThis codec can encode the frame contents using a run-length encoding algorithm. There are no checks that the decoded frame fits in the allocated buffer, leading to a heap-buffer-overflow.\nprocess_frame_obj initializes the buffers based on the frame resolution:\nWe recommend upgrading to version 8.0 or beyond.", "A flaw was found in FFmpeg. This vulnerability allows a heap-buffer-overflow via decoding a SANM (Software Audio and Music, ANIM v0 variant) file frame with run-length encoded data using codec 48, due to insufficient buffer size checks." ],
  "statement" : "This flaw in FFmpeg can lead to a heap-buffer-overflow when processing a specially crafted SANM (ANIM v0 variant) file. The highest threat is to system availability, as an attacker on the same adjacent network could trigger a denial of service.",
