Description

WeeChat before allows a remote crash by sending a filename via DCC to the IRC plugin.

For Debian 7 'Wheezy', these problems have been fixed in version 0.3.8-1+deb7u2.

We recommend that you upgrade your weechat packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
