Synopsis

========

 

Multiple memory management errors in JasPer could result in execution

of arbitrary code or a Denial of Service.

 

Background

==========

 

The JasPer Project is an open-source initiative to provide a free

software-based reference implementation of the codec specified in the

JPEG-2000 Part-1 (jpeg2k) standard.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 media-libs/jasper < 1.900.1-r4 >= 1.900.1-r4

 

Description

===========

 

Two vulnerabilities have been found in JasPer:

 

* The jpc_cox_getcompparms function in libjasper/jpc/jpc_cs.c contains

an error that could overwrite certain callback pointers, possibly

causing a heap-based buffer overflow (CVE-2011-4516).

* The jpc_crg_getparms function in libjasper/jpc/jpc_cs.c uses an

incorrect data type, possibly causing a heap-based buffer overflow

(CVE-2011-4517).

 

Impact

======

 

A remote attacker could entice a user or automated system to process

specially crafted JPEG-2000 files with an application using JasPer,

possibly resulting in the execution of arbitrary code with the

privileges of the application, or a Denial of Service.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All JasPer users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r4"
