Gentoo Linux Security Advisory

Title: JasPer: User-assisted execution of arbitrary code (GLSA 201201-10)
Severity: normal
Exploitable: remote
Date: January 23, 2012
Bug(s): #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: media-libs/jasper
Vulnerable: < 1.900.1-r4
Unaffected: >= 1.900.1-r4
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r4"
