Tabs Mail Carrier 2.5.1 contains a buffer overflow vulnerability in the MAIL FROM SMTP command that allows remote attackers to execute arbitrary code by sending a crafted MAIL FROM parameter. Attackers can connect to the SMTP service on port 25 and send a malicious MAIL FROM command with an oversized buffer to overwrite the EIP register and execute a bind shell payload.
