WeeChat before 4.4.2 has an integer overflow and resultant buffer overflow at core/core-string.c when there are more than two billion items in a list. This affects stringfreesplitshared , stringfreesplit, stringfreesplitcommand, and stringfreesplittags.
Wee Enhanced Environment for Chat (aka WeeChat) 0.3.4 and earlier does not properly verify that the server hostname matches the domain name of the subject of an X.509 certificate, which allows man-in-the-middle attackers to spoof an SSL chat server via an arbitrary certificate, related to incorrect use of the GnuTLS API.
Heap-based buffer overflow in WeeChat 0.3.6 through 0.3.9 allows remote attackers to cause a denial of service (crash or hang) and possibly execute arbitrary code via crafted IRC colors that are not properly decoded.
The hookprocess function in the plugin API for WeeChat 0.3.0 through 0.3.9.1 allows remote attackers to execute arbitrary commands via shell metacharacters in a command from a plugin, related to "shell expansion."
logger.c in the logger plugin in WeeChat before 1.9.1 allows a crash via strftime date/time specifiers, because a buffer is not initialized.
WeeChat (aka Wee Enhanced Environment for Chat) 3.2 to 3.4 before 3.4.1 does not properly verify the TLS certificate of the server, after certain GnuTLS options are changed, which allows man-in-the-middle attackers to spoof a TLS chat server via an arbitrary certificate. NOTE: this only affects situations where weechat.network.gnutlscasystem or weechat.network.gnutlscauser is changed without a WeeChat restart.
