Synopsis ========
Two vulnerabilities have been found in WeeChat, the worst of which may allow execution of arbitrary code.
Background ==========
Wee Enhanced Environment for Chat (WeeChat) is a light and extensible console IRC client.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-irc/weechat < 0.3.9.2 >= 0.3.9.2
Description ===========
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.
Resolution ==========
All WeeChat users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-irc/weechat-0.3.9.2"
