Multiple buffer overflows in the IMAILAPILib ActiveX control (IMailAPI.dll) in Ipswitch IMail Server before 2006.2 allow remote attackers to execute arbitrary code via the (1) WebConnect and (2) Connect members in the (a) IMailServer control; (3) Sync3 and (4) Init3 members in the (b) IMailLDAPService control; and the (5) SetReplyTo member in the (c) IMailUserCollection control.

Multiple buffer overflows in the IMAP service (imapd32.exe) in Ipswitch IMail Server 2006 before 2006.21 allow remote authenticated users to execute arbitrary code via the (1) Search or (2) Search Charset command.

Multiple buffer overflows in Ipswitch IMail Server 2006 before 2006.21 (1) allow remote attackers to execute arbitrary code via unspecified vectors in Imailsec and (2) allow attackers to have an unknown impact via an unspecified vector related to "subscribe."

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.

Format string vulnerability in the SMTP service in IMail Server 8.20 in Ipswitch Collaboration Suite (ICS) before 2.02 allows remote attackers to execute arbitrary code via format string specifiers to the (1) EXPN, (2) MAIL, (3) MAIL FROM, and (4) RCPT TO commands.

Buffer overflow in the IMAP daemon (IMAP4d32.exe) for Ipswitch Collaboration Suite (ICS) before 8.15 Hotfix 1 allows remote authenticated users to execute arbitrary code via a long EXAMINE command.

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.

Stack-based buffer overflow in the SMTP Daemon in Ipswitch Collaboration 2006 Suite Premium and Standard Editions, IMail, IMail Plus, and IMail Secure allows remote attackers to execute arbitrary code via a long string located after an '@' character and before a ':' character.

Buffer overflow in the IMAP daemon in Ipswitch Collaboration Suite 2006.02 and earlier allows remote authenticated users to execute arbitrary code via a long FETCH command.

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.

Multiple stack-based buffer overflows in the IMAP server in IMail 8.12 and 8.13 in Ipswitch Collaboration Suite (ICS), and other versions before IMail Server 8.2 Hotfix 2, allow remote attackers to execute arbitrary code via a LOGIN command with (1) a long username argument or (2) a long username argument that begins with a special character.

Stack-based buffer overflow in the IMAP daemon (IMAPD32.EXE) in IMail 8.13 in Ipswitch Collaboration Suite (ICS), and other versions before IMail Server 8.2 Hotfix 2, allows remote authenticated users to execute arbitrary code via a STATUS command with a long mailbox name.
