Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-136 - A buffer overflow is causing a crash or freeze of WeeChat (0.36 to 0.39) when decoding IRC colors in strings. The packages have been patched to fix this problem. Untrusted command for function hook_process in WeeChat before 0.3.9.2 could lead to execution of commands, because of shell expansions (so the problem is only caused by some scripts, not by WeeChat itself).
