jasper vulnerability
============================================================================

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

JasPer could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- jasper: Library for manipulating JPEG-2000 files

Details:

Jose Duart discovered that JasPer incorrectly handled certain malformed
JPEG-2000 image files. If a user were tricked into opening a specially
crafted JPEG-2000 image file, a remote attacker could cause JasPer to crash
or possibly execute arbitrary code with user privileges.

Update instructions:

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

Ubuntu 14.10:
  libjasper1                      1.900.1-debian1-2ubuntu0.1

Ubuntu 14.04 LTS:
  libjasper1                      1.900.1-14ubuntu3.1

Ubuntu 12.04 LTS:
  libjasper1                      1.900.1-13ubuntu0.1
