USN-3295-1: JasPer vulnerabilities
Ubuntu Security Notice USN-3295-1
18th May, 2017
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Several security issues were fixed in JasPer.
- jasper - Library for manipulating JPEG-2000 files
It was discovered that JasPer incorrectly handled certain malformed
JPEG-2000 image files. If a user or automated system using JasPer were
tricked into opening a specially crafted image, an attacker could exploit
this to cause a denial of service or possibly execute code with the
privileges of the user invoking the program.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 16.04 LTS:
- libjasper1 1.900.1-debian1-2.4ubuntu1.1
- Ubuntu 14.04 LTS:
- libjasper1 1.900.1-14ubuntu3.4
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
