USN-4199-1: libvpx vulnerabilities

25 November 2019

Several security issues were fixed in libvpx.



  • libvpx - VP8 and VP9 video codec


It was discovered that libvpx did not properly handle certain malformed
WebM media files. If an application using libvpx opened a specially crafted
WebM file, a remote attacker could cause a denial of service, or possibly
execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.04
Ubuntu 18.04
Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
