6.8 - USN-2919-1

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:
