Releases

• Ubuntu 19.04
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• libvpx - VP8 and VP9 video codec

Details

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

• libvpx5 - 1.7.0-3ubuntu0.19.04.1

Ubuntu 18.04

• libvpx5 - 1.7.0-3ubuntu0.18.04.1

Ubuntu 16.04

• libvpx3 - 1.5.0-2ubuntu1.1

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