CVE-ID : CVE-2017-8073
Package : weechat
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-253
The package weechat before version 1.7.1-1 is vulnerable to denial of
service.
Upgrade to 1.7.1-1.
The problem has been fixed upstream in version 1.7.1.
Use the following workaround for weechat>=1.1:
/trigger add irc_dcc_quotes modifier “irc_in_privmsg” "${arguments}
=~ ^[^ ]+ :${\x01}DCC SEND ${\x22} " “/.*//”
WeeChat before 1.7.1 allows a remote crash by sending a filename via
DCC to the IRC plugin. This occurs in the
irc_ctcp_dcc_filename_without_quotes function during quote removal,
which results in a buffer overflow.
A remote attacker is able to crash the application via a maliciously
crafted DCC-request.
