Synopsis
========
The NBD server is vulnerable to a buffer overflow that may result in
the execution of arbitrary code.
Background
==========
The NBD Tools are the Network Block Device utilities allowing one to
use remote block devices over a TCP/IP network. It includes a userland
NBD server.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-block/nbd lt; 2.8.2-r1 gt;= 2.8.2-r1
Description
===========
Kurt Fitzner discovered that the NBD server allocates a request buffer
that fails to take into account the size of the reply header.
Impact
======
A remote attacker could send a malicious request that can result in the
execution of arbitrary code with the rights of the NBD server.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All NBD Tools users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=sys-block/nbd-2.8.2-r1"
