CVE-2007-4411

CWE-Other
 
 
ircu 2.10.12.05 and earlier allows remote attackers to discover the hidden IP address of arbitrary +x users via a series of /silence commands with (1) CIDR mask arguments or (2) certain other arguments that represent groups of IP addresses, then monitoring CTCP ping replies.

 
 
CVE-2007-4410

CWE-Other
 
 
ircu 2.10.12.05 and earlier does not properly synchronize a kick action in certain cross scenarios, which allows remote authenticated operators to prevent later kick or de-op actions from non-local ops.

 
 
CVE-2007-4409

CWE-Other
 
 
Race condition in ircu 2.10.12.01 through 2.10.12.05 allows remote attackers to set a new Apass during a netburst by arranging for ops privilege to be granted before the mode arrives.

 
 
CVE-2007-4408

CWE-Other
 
 
ircu 2.10.12.05 and earlier ignores timestamps in bounces, which allows remote attackers to take over a channel during a netjoin by causing a bounce while a server with an older version of the channel is linking.

 
 
CVE-2007-4407

CWE-Other
 
 
ircu 2.10.12.03 and 2.10.12.04 does not associate a timestamp with ops privilege on an unused channel (zannel), which allows remote attackers to (1) set or remove certain channel modes via a "netriding" attack or (2) take over a channel by joining an unlinked server with the A/Upass and then setting a new Apass.

 
 
CVE-2007-4406

CWE-Other
 
 
ircu 2.10.12.01 through 2.10.12.04 does not remove ops privilege after a join from a server with an older timestamp (TS), which allows remote attackers to gain control of a channel during a split.

 
 
CVE-2007-4405

CWE-Other
 
 
ircu 2.10.12.02 through 2.10.12.04 allows remote attackers to cause a denial of service (memory and bandwidth consumption) by creating a large number of unused channels (zannels).

 
 
CVE-2007-4404

CWE-Other
 
 
ircu 2.10.12.01 allows remote attackers to (1) cause a denial of service (flood wallops) by joining two channels with certain long names that differ in the final character, which triggers a protocol violation and (2) cause a denial of service (daemon crash) via a "J 0:#channel" message on a channel without an apass; and (3) allows remote authenticated operators to cause a denial of service (daemon crash) via a remote "names -D" command.
