CVE-2017-14056 describes a Denial of Service (DoS) vulnerability in FFmpeg versions prior to 3.3.3, specifically within the libavformat/rl2.c component. This medium-severity flaw (CVSS 6.5) allows an unauthenticated attacker to trigger excessive CPU and memory consumption by providing a crafted RL2 file with a large "frame_count" but insufficient data, leading to infinite loops during header parsing. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.
