SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201201-10 (JasPer: User-assisted execution of arbitrary code)
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).
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.
There is no known workaround at this time.
SolutionAll JasPer users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/jasper-1.900.1-r4'
