Novell · Novell Netmail · CVE-2006-6424
**Name of the Vulnerable Software and Affected Versions**
Novell NetMail versions prior to 3.52e FTF2
**Description**
The issue is related to multiple buffer overflows that allow remote attackers to execute arbitrary code. This can be achieved in two ways: by appending literals to certain IMAP verbs when specifying command continuation requests to IMAPD, resulting in a heap overflow, or via crafted arguments to the STOR command to the Network Messaging Application Protocol (NMAP) daemon, resulting in a stack overflow.
**Recommendations**
For Novell NetMail versions prior to 3.52e FTF2, update to version 3.52e FTF2 or later to resolve the issue. As a temporary workaround, consider restricting access to the IMAPD and NMAP daemon to minimize the risk of exploitation. Avoid using crafted arguments to the STOR command until the issue is resolved.
