Description Sam Fowler 2018-02-21 03:59:37 UTC
libwebm through versions, which is bundled in chromium, is vulnerable to an out of bounds read issue. The function common/libwebm_util.cc:ParseVP9SuperFrameIndex() does not validate child_frame_length data obtained from a .webm file, which can cause an information leak, denial of service or other potential unspecified impact.
