CVE-2016-10251

Integer overflow in the jpc_pi_nextcprl function in jpc_t2cod.c in JasPer before 1.900.20 allows remote attackers to have unspecified impact via a crafted file, which triggers use of an uninitialized value.

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.
