Network Block Device (NBD) Server Request Handling Remote Overflow

high Nessus Plugin ID 20341
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote service is affected by a buffer overflow vulnerability.


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.


Upgrade to NBD 2.8.3 or later.
