Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200812-18
(JasPer: User-assisted execution of arbitrary code)

Marc Espie and Christian Weisgerber have discovered multiple
vulnerabilities in JasPer:
Multiple integer overflows might allow for insufficient memory
allocation, leading to heap-based buffer overflows (CVE-2008-3520).
The jas_stream_printf() function in libjasper/base/jas_stream.c uses
vsprintf() to write user-provided data to a static to a buffer, leading
to an overflow (CVE-2008-3522).

Impact :

Remote attackers could entice a user or automated system to process
specially crafted jpeg2k files with an application using JasPer,
possibly leading to the execution of arbitrary code.

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-r3'

Risk factor :

Critical / CVSS Base Score : 10.0
CVSS Temporal Score : 8.7
Public Exploit Available : false
