8.8 · HIGHOverview
CVE-2018-6406 is a high-severity vulnerability affecting webmproject libwebm. It was published on January 30, 2018 and has a CVSS 3.0 base score of 8.8 (HIGH).
This vulnerability has a CVSS 3.0 base score of 8.8, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from webmproject. Update libwebm to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
