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"
