jasper vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10
- Ubuntu 14.04 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)
