CVE-2018-6406 (GCVE-0-2018-6406)

Vulnerability from cvelistv5 – Published: 2018-01-30 21:00 – Updated: 2024-09-17 03:33

Summary

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.

Severity ?

No CVSS data available.
