libjpeg-turbo vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary:
libjpeg-turbo could be made to crash or run programs as your login if it
opened a specially crafted file.
Software Description:
- libjpeg-turbo: library for handling JPEG files
Details:
It was discovered that libjpeg-turbo incorrectly handled certain malformed
JPEG images. If a user or automated system were tricked into opening a
specially crafted JPEG image, a remote attacker could cause libjpeg-turbo
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:
libjpeg-turbo8 1.5.2-0ubuntu5.18.04.1
Ubuntu 17.10:
libjpeg-turbo8 1.5.2-0ubuntu5.17.10.1
Ubuntu 16.04 LTS:
libjpeg-turbo8 1.4.2-0ubuntu3.1
Ubuntu 14.04 LTS:
libjpeg-turbo8 1.3.0-0ubuntu2.1
In general, a standard system update will make all the necessary changes.
