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.

PROVIDED AND/OR DISCOVERED BY:
Ejovi Nuwere, SecurityLab Technologies.
