It has been reported that Ipswitch IMail server is prone to an SMTP HELO command argument buffer overflow vulnerability.
|
|
|
|
The issue presents itself likely due to insufficient bounds checking performed when handling malicious SMTP HELO command arguments of excessive length. It has been reported that a remote attacker may exploit this condition to trigger a denial of service in the affected daemon.
