GLSA 201201-10: JasPer: User-assisted execution of arbitrary code

http://security.gentoo.org/

Severity:	normal
Title:	JasPer: User-assisted execution of arbitrary code
Date:	01/23/2012
Bugs:	#394879
ID:	201201-10

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	Architecture(s)
media-libs/jasper	< 1.900.1-r4	>= 1.900.1-r4	All supported architectures

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"
