Title: E-MailClub Buffer Overflow Vulnerability
Severity: HIGH
Description:
Certain versions of EmailClub, a mail server package by Admiral Systems Inc. are vulnerable to a remote buffer overflow. This overflow is exploitable via EmailClub's POP3 server which fails to perform proper bounds checking on the 'From:' header on incoming e-mail.
This overflow will lead to a complete compromise of the Windows 95/98 target machine. It may well also affect Windows NT installations in the same manner. It is unclear though if EmailClub run with ADMIN privileges under Windows NT installations.
Affected Products:
- Admiral Systems EmailClub 1.0.0 .0.5
