Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The 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).

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.

Solution :

All JasPer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/jasper-1.900.1-r4'

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.0
