Ubuntu Security Notice USN-4199-1
November 25, 2019

libvpx vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in libvpx.

Software Description:
- 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 LTS:
  libvpx5                         1.7.0-3ubuntu0.18.04.1

Ubuntu 16.04 LTS:
  libvpx3                         1.5.0-2ubuntu1.1

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