Extremail Buffer Overflow And DNS Spoofing Vulnerabilities

eXtremail is prone to a buffer-overflow issue and DNS-spoofing vulnerabilities that could allow malicious users to trigger denial-of-service conditions, execute remote code with superuser privileges, and perform DNS-spoofing attacks on clients on unprotected networks.

These issues affect eXtremail 2.1 and 2.1.1; other versions may also be affected.
