Microsoft has released security
updates that are impacting some
security AV vendors, causing some
of their customers using Windows
7, Windows 8.1, Windows 2008 R2,
and Windows 2012 to occasionally
experience system fails or hangs
during boot up after application
of the update. |
|
A
small number of Sophos customers
have reported experiencing this
issue. Sophos is working very
closely with Microsoft to resolve
the issue. Microsoft has
introduced a temporary block to
stop computers not already
affected from applying the latest
Windows security update.
Additionally, we have a work
around for those impacted
customers.
|
|
How do I know if my
customer is impacted?
|
|
To be
impacted, customers must meet all
the criteria below. If they do not
meet all the criteria, then they
are not impacted.
|
|
1. |
Running
Windows 7, Windows 8.1, Windows
2008 R2, or Windows 2012
|
|
2. |
Running
any Sophos Windows endpoint or
server product except Sophos
Central Intercept X. (Note: this
does impact Intercept X Advanced
and Intercept X Advanced with
EDR.)
|
|
3. |
Have
applied the latest Windows
security update and have
rebooted after the update is
complete
Important note:
If customers have not yet
rebooted, they should uninstall
the latest Microsoft security
update before rebooting
|
|
As the majority
of Sophos customers do not seem to
be affected, it is possible that
during the ongoing investigation
additional criteria will be added
to further limit the scope of
impacted customers. KBA
133945 will continue to be
updated with the latest
information. |
|
How do
I help an impacted customer?
|
|
The
latest information about this
issue and remediation steps are
documented in KBA
133945. |
|
We are
notifying all Sophos Endpoint
customers via email to inform them
of this situation. The KBA will
continue to be updated with the
latest information. |
