Description:
Ejovi Nuwere has reported a vulnerability in MultiTech MultiVoIP Gateway, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a boundary error when parsing SIP packets. This can be exploited to cause a buffer overflow via a specially crafted SIP packet with an INVITE field that is longer than 60 characters.

Successful exploitation causes the device to reboot.

The vulnerability has been reported in models MVP130, MVP210, MVP410, MPV810, MVP2410, and MVP3010.

Solution:
The vulnerability has been fixed in the X.08 release, which is available from the vendor.
