The IMAP service for MailEnable Professional and Enterprise Edition 2.0 through 2.34, Professional Edition 1.6 through 1.83, and Enterprise Edition 1.1 through 1.40 allows remote attackers to cause a denial of service (crash) via unspecified vectors that trigger a null pointer dereference, as addressed by the ME-10023 hotfix, and a different issue than CVE-2006-6423. NOTE: some details were obtained from third party information.

Multiple stack-based buffer overflows in the IMAP module (MEIMAPS.EXE) in MailEnable Professional 1.6 through 1.82 and 2.0 through 2.33, and MailEnable Enterprise 1.1 through 1.30 and 2.0 through 2.33 allow remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a long argument to the (1) EXAMINE or (2) SELECT command.

Buffer overflow in NTLM authentication in MailEnable Professional 2.0 and Enterprise 2.0 allows remote attackers to execute arbitrary code via "the signature field of NTLM Type 1 messages".

The NTLM authentication in MailEnable Professional 2.0 and Enterprise 2.0 allows remote attackers to (1) execute arbitrary code via unspecified vectors involving crafted base64 encoded NTLM Type 3 messages, or (2) cause a denial of service via crafted base64 encoded NTLM Type 1 messages, which trigger a buffer over-read.
