Affected software

eggdrop (1.6.19 only, not 1.6.19+ctcpfix)
windrop (1.6.19 only, not 1.6.19+ctcpfix)
all eggdrop/windrop versions and packages which apply Nico Goldes
patch for CVE-2007-2807/SA25276 See: [1]

Vulnerability details

The SA25276 patch ([1]) uses strncpy to fix a buffer overflow vulnerability
in src/mod/server.mod/servmsg.c (gotmsg). The last argument is not checked
for being non-negative, but that can happen if ctcpbuf is "". That causes
a remote crash vulnerability to be exploited by anyone connected to the same
IRC network as eggdrop. The SA25276 patch has been applied to the eggdrop1.6.18
debian package and was later adopted by Eggheads into eggdrop1.6.19.

Dang, nice find.
