CVE-2007-5226: Dircproxy

Medium severity, CVSS 5.0. EPSS: 1.7% chance of exploitation in the next 30 days.

irc_server.c in dircproxy 1.2.0 and earlier allows remote attackers to cause a denial of service (segmentation fault) via an ACTION command without a parameter, which triggers a NULL pointer dereference, as demonstrated using a blank /me message from irssi.
