High Nessus Plugin ID 73859


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


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.


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