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-200812-02
(enscript: User-assisted execution of arbitrary code)

Two stack-based buffer overflows in the read_special_escape() function
in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research
discovered a vulnerability related to the 'setfilename' command
(CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability
related to the 'font' escape sequence (CVE-2008-4306).

Impact :

An attacker could entice a user or automated system to process
specially crafted input with the special escapes processing enabled
using the '-e' option, possibly resulting in the execution of arbitrary
code.

Workaround :

There is no known workaround at this time.
