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

  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS

Summary

Several security issues were fixed in JasPer.

Software Description

  • 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.

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

libjasper1 - 1.900.1-debian1-2.4ubuntu1.1
