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"
