http://www.juniper.net/support/security/alerts/screenos-sshv1-2.txtHow to get ScreenOS:
Customers with a valid product warranty or a support contract may

please call your regional Juniper Networks TAC (JTAC) center. To get a

http://www.juniper.net/entitlement/setupAccountInfo.doSelect option 2 from the telephone menu and be sure to select the
correct product from the phone tree. Once connected with an engineer
state that you are calling in regards to a Security Advisory and provide
the title of this notice as evidence of your entitlement to the
specified release.
Please note that customers with expired support contracts will be
provided only with the software update for the version of software that
they are currently using, when that version becomes available.
As with any new software installation, Juniper Networks customers
planning to upgrade to any version of ScreenOS should carefully read the
release notes and other relevant documentation before beginning any
upgrade.
Juniper Networks would like to thank Mark Ellzey Thomas of NaviSite for
discovering this issue and working with us.
