CVE ID : CVE-2016-1577 CVE-2016-2089 CVE-2016-2116
Debian Bug : 812978 816625 816626

Several vulnerabilities were discovered in JasPer, a library for
manipulating JPEG-2000 files. The Common Vulnerabilities and Exposures
project identifies the following problems:

CVE-2016-1577

Jacob Baines discovered a double-free flaw in the
jas_iccattrval_destroy function. A remote attacker could exploit
this flaw to cause an application using the JasPer library to crash,
or potentially, to execute arbitrary code with the privileges of the
user running the application.

CVE-2016-2089

The Qihoo 360 Codesafe Team discovered a NULL pointer dereference
flaw within the jas_matrix_clip function. A remote attacker could
exploit this flaw to cause an application using the JasPer library
to crash, resulting in a denial-of-service.

CVE-2016-2116

Tyler Hicks discovered a memory leak flaw in the
jas_iccprof_createfrombuf function. A remote attacker could exploit
this flaw to cause the JasPer library to consume memory, resulting
in a denial-of-service.

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.900.1-13+deb7u4.

For the stable distribution (jessie), these problems have been fixed in
version 1.900.1-debian1-2.4+deb8u1.

We recommend that you upgrade your jasper packages.
