Description: iDEFENSE has reported a vulnerability in IMail Server, which can be exploited by malicious people to compromise a vulnerable system. The vulnerability is caused due to a boundary error in the LDAP daemon ("iLDAP.exe") when handling tags in LDAP messages. This can be exploited to cause a buffer overflow prior to authentication by sending specially crafted LDAP messages with overly long length tags to a vulnerable system. Successful exploitation allows execution of arbitrary code. The vulnerability has been reported in "iLDAP.exe" 3.9.15.10 included in IMail Server 8.03. However, other versions may also be affected. Solution: Apply 8.05 Hotfix 2. http://www.ipswitch.com/support/imail/releases/imail_professional/im805HF2.html Provided and/or discovered by: iDEFENSE Changelog: 2004-02-24: Added link to CERT.
