T. Hauck Jana Server POP3 Invalid Message Index Denial Of Service Vulnerability

Jana Server is a server for Microsoft Windows based systems. Jana Server provides a wide range of proxy servers, and a number of other services. A POP3 mail server is included.

Reportedly, Jana Server does not properly validate POP3 message index values received from the client. A malicious user may specify a large, invalid message index. The server will attempt to access this message and crash due to a memory error, resulting in a denial of service condition.
