Gentoo: GLSA-201201-10 Normal: JasPer Arbitrary Code Threat
gentoo
January 23, 2012
Multiple memory management errors in JasPer could result in execution of arbitrary code or a Denial of Service.
Summary
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).
Resolution
All JasPer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/jasper-1.900.1-r4"
