The Ipswitch IMail Server is vulnerable to a buffer overflow

Vulnerability Note VU#542197

Original Release Date: 2006-12-07 | Last Revised: 2006-12-07


The Ipswitch IMail Server is vulnerable to a buffer overflow. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code or cause a denial-of-service condition.


According to Ipswitch Security Advisory 20061101:

A vulnerability that allowed remote attackers to execute arbitrary code within the SMTP daemon was recently discovered. Because of compiler options used to prevent buffer overflow exploitation, arbitrary code execution does not work in 8.2x or 2006, but the exploit can be used to create a Denial of Service condition. Versions 8.1x and lower are vulnerable to the arbitrary code execution and versions prior to 8.1x may also be vulnerable.
Note that we are aware of publicly available exploit code for this vulnerability and have received reports of successful exploitation.


A remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial of service condition.
