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-201405-03
(WeeChat: Multiple vulnerabilities)

Two vulnerabilities have been discovered in WeeChat:
The hook_process() function does not properly handle shell expansions
(CVE-2012-5534).
WeeChat does not properly decode colors which could cause a
heap-based buffer overflow (CVE-2012-5854).

Impact :

A remote attacker could entice a user to open a specially crafted script
or send messages with specially crafted colors, possibly resulting in
execution of arbitrary code with the privileges of the process, or a
Denial of Service condition.

There is no known workaround at this time.
