|            |Small Business Edition may be susceptible to a privilege        |
|Description:|escalation vulnerability, which is a type of issue whereby an   |
|            |attacker may attempt to compromise the software application to  |
|            |gain elevated access to resources that are normally protected   |
|            |from an application or user.                                    |


The mentioned issue was validated by the product team engineers. A Symantec
Endpoint Protection update, version 14.2 RU1 , and Symantec Endpoint Protection
Small Business Edition update, version 12.1 RU6 MP10c (12.1.7491.7002) , have
been released which address the aforementioned issue. The latest releases and
patches for Symantec Endpoint Protection and Symantec Endpoint Protection Small
Business Edition are available to customers through normal support channels. At
this time, Symantec is not aware of any exploitations or adverse customer
impact from these issues.

Note : for customers who are currently not using Application and Device
Control, you can use the instructions in the following technote to mitigate the
current issue in the interim.


Symantec recommends the following measures to reduce risk of attack:

  o Restrict access to administrative or management systems to authorized
    privileged users.
  o Restrict remote access to trusted/authorized systems only.
  o Run under the principle of least privilege, where possible, to limit the
    impact of potential exploit.
  o Keep all operating systems and applications current with vendor patches.
  o Follow a multi-layered approach to security. At a minimum, run both
    firewall and anti-malware applications to provide multiple points of
    detection and protection for both inbound and outbound threats.
  o Deploy network and host-based intrusion detection systems to monitor
    network traffic for signs of anomalous or suspicious activity. This may aid
    in the detection of attacks or malicious activity related to the
    exploitation of latent vulnerabilities.
