Alt-N MDaemon Multiple Remote Pre-Authentication POP3 Buffer Overflow Vulnerabilities

Alt-N MDaemon Multiple Remote Pre-Authentication POP3 Buffer Overflow Vulnerabilities

Alt-N MDaemon POP3 Server is susceptible to multiple remote buffer-overflow vulnerabilities. The issues are due to the application's failure to properly bounds-check user-supplied input before copying it to insufficiently sized memory buffers.

These issues allow remote, unauthenticated attackers to execute arbitrary machine code in the context of affected servers. This may facilitate the compromise of affected computers.

MDaemon versions 8 and 9 are reported to be vulnerable; previous versions may be affected as well.
