libraw vulnerabilities
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

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

Software Description:
- libraw: raw image decoder library

Details:

It was discovered that LibRaw incorrectly handled photo files. If 
a user or
automated system were tricked into processing a specially crafted 
photo file, a
remote attacker could cause applications linked against LibRaw 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:
  libraw16                        0.18.8-1ubuntu0.2

Ubuntu 16.04 LTS:
  libraw15                        0.17.1-1ubuntu0.4

Ubuntu 14.04 LTS:
  libraw9                         0.15.4-1ubuntu0.3

After a standard system update you need to restart your session to 
make all the
necessary changes.
