GFI » Mailsecurity : Security Vulnerabilities, CVEs, Published In 2005

Buffer overflow in the HTTP management interface for GFI MailSecurity 8.1 allows remote attackers to execute arbitrary code via long headers such as (1) Host and (2) Accept in HTTP requests. NOTE: the vendor suggests that this issues is "in an underlying Microsoft technology" which, if true, could mean that the overflow affects other products as well.

A bug in the HTML parser in a certain Microsoft HTML library, as used in various third party products, may allow remote attackers to cause a denial of service via certain strings, as reported in GFI MailEssentials for Exchange 9 and 10, and GFI MailSecurity for Exchange 8, which causes emails to remain in IIS or Exchange mail queues.
