Synopsis
Multiple memory management errors in JasPer could result in
execution of arbitrary code or a Denial of Service.
2.
Impact Information
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.
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.

Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All JasPer users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r4"
|
