Description


Some vulnerabilities have been reported in Ipswitch IMail Server and Collaboration Suite, which can be exploited by malicious users and malicious people to compromise a vulnerable system.

1) A boundary error in the processing of the IMAP "SEARCH" command "SENTON" search key can be exploited to cause a stack-based buffer overflow via an overly long, unquoted argument.

Successful exploitation allows execution of arbitrary code, but requires a valid user account.

2) A boundary error in the processing of the IMAP "SEARCH CHARSET" command can be exploited to cause a heap-based buffer overflow.

Successful exploitation allows execution of arbitrary code, but requires a valid user account.

Vulnerabilities #1 and #2 are reported in version 6.8.8.1 of imapd32.exe. Prior versions may also be affected.

3) A boundary error exists in Imailsec.dll when authenticating users and can be exploited to cause a heap-based buffer overflow.

Successful exploitation of this vulnerability allows execution of arbitrary code.

4) A boundary error exists in the IMAP daemon within the processing of the IMAP "SUBSCRIBE" command, which can be exploited to cause a stack-based buffer overflow, by sending an overly long string as an argument to the affected function.

Successful exploitation of this vulnerability allows execution of arbitrary code, but requires valid user credentials.

Vulnerabilities #3 and #4 are reported in Ipswitch IMail Server and Collaboration Suite prior to version 2006.21.
