CVE-2016-9600

JasPer before version 2.0.10 is vulnerable to a null pointer dereference was found in the decoded creation of JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash.

The jasper package has been updated and patched to fix several security issues.

These are all security issues fixed in the jasper-2.0.33-1.2 package on the GA media of openSUSE Tumbleweed.

This update for jasper fixes the following issues:

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.
