Several security issues were fixed in JasPer.

Releases

Packages

  • jasper - Library for manipulating JPEG-2000 files

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04
Ubuntu 14.04

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