Krystian Kloskowski has discovered some vulnerabilities in Eudora, which can be exploited by malicious people to compromise a user's system.
1) A boundary error when processing SMTP server reply strings can be exploited to cause a stack-based buffer overflow via an overly long, specially crafted SMTP reply string.
Successful exploitation allows execution of arbitrary code when a user sends an email, but requires that the user is tricked into connecting to a malicious SMTP server by editing the application's settings. Also, the user has to click on "Cancel" when presented with the buffer overflow warning message box.
2) A boundary error when processing IMAP FLAGS responses can be exploited to cause a stack based buffer overflow via a specially crafted response containing overly long strings.
Successful exploitation allows execution of arbitrary code, but requires that a user is tricked into connecting to a malicious IMAP server.
The vulnerabilities are confirmed in version 22.214.171.124. Other versions may also be affected.
