Ubuntu Security Notice USN-2919-1
March 03, 2016

jasper vulnerabilities
==========================================================================

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

- Ubuntu 15.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in JasPer.

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

Details:

Jacob Baines discovered that JasPer incorrectly handled ICC color profiles
in 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.
(CVE-2016-1577)

Tyler Hicks discovered that JasPer incorrectly handled memory when
processing 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 consume memory, resulting in a denial of service.
(CVE-2016-2116)

Update instructions:

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

Ubuntu 15.10:
  libjasper1                      1.900.1-debian1-2.4ubuntu0.15.10.1

Ubuntu 14.04 LTS:
  libjasper1                      1.900.1-14ubuntu3.3

Ubuntu 12.04 LTS:
  libjasper1                      1.900.1-13ubuntu0.3

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