Description Pedro Sampaio 2020-01-08 14:59:11 UTC

In libvpx, there is a possible resource exhaustion due to improper input validation. This could lead to remote denial of service with no additional execution privileges needed. User interaction is needed for exploitation.

rhel7 is not affected, libvpx 1.3.0 does not include the mkv parser (yet)
