==========================================================================

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS

Summary:

Several security issues were fixed in LibRaw.

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 20.04 LTS:
libraw19 0.19.5-1ubuntu1.1

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