CVE-2018-6406
Last modified
CVE-2018-6406 is a vulnerability of currently unknown severity. The function ParseVP9SuperFrameIndex in common/libwebm_util.cc in libwebm through 2018-01-30 does not validate the child_frame_length data obtained from a .webm file, which allows remote attackers to cause an information leak or a denial of service (heap-based buffer over-read and later out-of-bounds write), or possibly have unspecified other impact.. EPSS estimates a 2.04% chance of exploitation in the next 30 days.
