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.

Buffer overflow in IMail Client 9.22, as shipped with IPSwitch IMail Server 2006.22, allows remote attackers to execute arbitrary code via a long boundary parameter in a multipart MIME e-mail message.

Heap-based buffer overflow in iaspam.dll in the SMTP Server in Ipswitch IMail Server 8.01 through 8.11 allows remote attackers to execute arbitrary code via a set of four different e-mail messages with a long boundary parameter in a certain malformed Content-Type header line, the string "MIME" by itself on a line in the header, and a long Content-Transfer-Encoding header line.

Multiple buffer overflows in Ipswitch IMail before 2006.21 allow remote attackers or authenticated users to execute arbitrary code via (1) the authentication feature in IMailsec.dll, which triggers heap corruption in the IMail Server, or (2) a long SUBSCRIBE IMAP command, which triggers a stack-based buffer overflow in the IMAP Daemon.

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."

Ipswitch IMail Server 2006 before 2006.21 allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors involving an "overwritten destructor."

IMail POP3 daemon uses weak encryption, which allows local users to read files.

Buffer overflow in the login functions in IMAP server (imapd) in Ipswitch IMail 5.0 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via (1) a long user name or (2) a long password.

IPswitch WS_FTP allows local users to gain additional privileges and modify or add mail accounts by setting the "flags" registry key to 1920.

IPSwitch IMail 6.0.5 allows remote attackers to cause a denial of service using the SMTP AUTH command by sending a base64-encoded user password whose length is between 80 and 136 bytes.

Buffer overflow in IPSwitch IMail SMTP server 6.06 and possibly prior versions allows remote attackers to execute arbitrary code via a long From: header.

Ipswitch IMail 7.0.4 and earlier allows attackers with administrator privileges to read and modify user alias and mailing list information for other domains hosted by the same server via the (1) aliasadmin or (2) listadm1 CGI programs, which do not properly verify that an administrator is the administrator for the target domain.

POP3 Server for Ipswitch IMail 7.04 and earlier generates different responses to valid and invalid user names, which allows remote attackers to determine users on the system.

Ipswitch Imail 6.0 allows remote attackers to cause a denial of service via a large number of connections in which a long Host: header is sent, which causes a thread to crash.

The web server in IPSWITCH IMail 6.04 and earlier allows remote attackers to read and delete arbitrary files via a .. (dot dot) attack.

Buffer overflow in Ipswitch IMail Service 5.0 allows an attacker to cause a denial of service (crash) and possibly execute arbitrary commands via a long URL.

Ipswitch IMail 7.04 and earlier uses predictable session IDs for authentication, which allows remote attackers to hijack sessions of other users.

Directory traversal vulnerability in readmail.cgi for Ipswitch IMail 7.04 and earlier allows remote attackers to access the mailboxes of other users via a .. (dot dot) in the mbx parameter.

The webmail interface for Ipswitch IMail 7.04 and earlier allows remote authenticated users to cause a denial of service (crash) via a mailbox name that contains a large number of . (dot) or other characters to programs such as (1) readmail.cgi or (2) printmail.cgi, possibly due to a buffer overflow that may allow execution of arbitrary code.
