libwebp vulnerability

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

- Ubuntu 18.04 LTS (Available with Ubuntu Pro)


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

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


USN-6369-1 fixed a vulnerability in libwebp. This update provides the
corresponding update for Ubuntu 18.04 LTS.

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 18.04 LTS (Available with Ubuntu Pro):
  libwebp6                        0.6.1-2ubuntu0.18.04.2+esm1
  libwebpdemux2                   0.6.1-2ubuntu0.18.04.2+esm1
  libwebpmux3                     0.6.1-2ubuntu0.18.04.2+esm1

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