Netscape NSS Library SSLv2 Challenge Overflow

This script is Copyright (C) 2004-2013 Digital Defense


Synopsis :

The remote service is susceptible to a buffer overflow attack.

Description :

The remote host seems to be using the Mozilla Network Security
Services (NSS) Library, a set of libraries designed to support the
development of security-enabled client/server applications.

There seems to be a flaw in the remote version of this library, in the
SSLv2 handling code, that may allow an attacker to cause a heap
overflow and therefore execute arbitrary commands on the remote host.
To exploit this flaw, an attacker needs to send a malformed SSLv2
'hello' message to the remote service.

Solution :

Upgrade the remote service to use NSS 3.9.2 or newer.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.2
(CVSS2#E:F/RL:OF/RC:C)
