  "title": "libde265-0: libde265 is an open source implementation of the h.265 video codec",
  "description": "libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes \u0060decoder_context::read_slice_NAL()\u0060 (\u0060libde265/decctx.cc:481\u0060) to attach slice headers to a finished picture object that has no active image unit, resulting in attacker-controlled unbounded heap growth. The retained headers are never freed until the picture is released, which may not happen during continuous streaming. Version 1.0.20 patches the issue.",
