4) Description of Vulnerability
Secunia Research has discovered a vulnerability in MailEnable, which
can be exploited by malicious people to compromise a vulnerable
system.
The vulnerability is caused due to a boundary error in the POP service
when handling arguments passed to the "PASS" command. This can be
exploited to cause a stack-based buffer overflow by passing an overly
long, specially crafted string as argument to the affected command.
Successful exploitation allows execution of arbitrary code.
The Common Vulnerabilities and Exposures (CVE) project has assigned
CVE-2006-6605 for the vulnerability.
