Premium Anti-Spam in Ipswitch IMail Secure Server 2006 and Collaboration Suite 2006 Premium, when using a certain .dat file in the StarEngine /data directory from 20060630 or earlier, does not properly receive and implement bullet signature updates, which allows context-dependent attackers to use the server for spam transmission.
The IMAP daemon (IMAPD32.EXE) in Ipswitch Collaboration Suite (ICS) allows remote attackers to cause a denial of service (CPU consumption) via an LSUB command with a large number of null characters, which causes an infinite loop.
The IM Server (aka IMserve or IMserver) 2.0.5.30 and probably earlier in Ipswitch Instant Messaging before 2.07 in Ipswitch Collaboration Suite (ICS) allows remote attackers to cause a denial of service (daemon crash) via certain data to TCP port 5179 that overwrites a destructor, as reachable by the (1) DoAttachVideoSender, (2) DoAttachVideoReceiver, (3) DoAttachAudioSender, and (4) DoAttachAudioReceiver functions.
The IMAP server in IMail Server 8.20 in Ipswitch Collaboration Suite (ICS) before 2.02 allows remote attackers to cause a denial of service (crash) via a long argument to the LIST command, which causes IMail Server to reference invalid memory.
