Ubuntu Security Notice USN-4971-2
June 10, 2021

libwebp vulnerabilities
==========================================================================

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

- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

libwebp could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- libwebp: Lossy compression of digital photographic images.

Details:

USN-4971-1 fixed several vulnerabilities in libwebp. This update provides
the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.

Original advisory details:

 It was discovered that libwebp incorrectly handled certain malformed
 images. If a user or automated system were tricked into opening a specially
 crafted image file, a remote attacker could use this issue to cause libwebp
 to crash, resulting in 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 16.04 ESM:
  libwebp5                        0.4.4-1ubuntu0.1~esm1
  libwebpdemux1                   0.4.4-1ubuntu0.1~esm1
  libwebpmux1                     0.4.4-1ubuntu0.1~esm1

Ubuntu 14.04 ESM:
  libwebp5                        0.4.0-4ubuntu0.1~esm1
  libwebpdemux1                   0.4.0-4ubuntu0.1~esm1
  libwebpmux1                     0.4.0-4ubuntu0.1~esm1

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