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.
 Workaround :

 There is no known workaround at this time.

Solution

All WeeChat users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-irc/weechat-0.3.9.2'
