Network Block Device (NBD) Server Request Handling Remote Overflow

high Nessus Plugin ID 20341

Language:

Synopsis

The remote service is affected by a buffer overflow vulnerability.

Description

The version of the Network Block Device (NBD) server installed on the remote host does not properly check the size of read requests before filling a dynamically-allocated buffer. Using a specially crafted read request, an attacker can overwrite this buffer, which could crash the affected server or allow for the execution of arbitrary code.

Solution

Upgrade to NBD 2.8.3 or later.
