Overview
Symantec's Client Intrusion Detection System (CIDS) driver may cause a system
crash when interacting with a specifically-crafted Portable Executable file.
Affected Products
Product Version Builds Solution(s)
Norton Security Windows Only All Update to CIDS v15.1.2 via LiveUpdate Defs
Symantec Endpoint Protection Windows Only All Update to CIDS v15.0.6 via LiveUpdate Defs
Details
Symantec was notified of a system crash, Denial of Service (DoS) in the CIDS
engine driver when interacting with a specifically-crafted portable-executable
(PE) files. A malicious individual would first need to entice an authorized
user to download a malformed PE file either through opening an email
attachment, downloading a malicious document or application or by enticing the
user to visit a web site where a malicious file could be downloaded to their
system. Once downloaded, the malicious file must be manipulated on the
targeted system hard drive to interact with the vulnerable CIDS engine.
Sufficiently malformed, the code would execute at the kernel-level with system
privileges causing memory corruption resulting in a system crash.
Symantec Response
Symantec engineers have addressed this in the latest CIDS engine update
release effective 7/7/2016 delivered to customers via LiveUpdate with normal
definition and signature updates.
Update Information
Norton Security and SEP products that ship with the CIDS engine and regularly
launch and run either automatic or manual LiveUpdate should already have
received an updated CIDS engine version addressing this issue. However, to
ensure all available updates have been applied, users should manually launch
and run LiveUpdate in Interactive mode as follows:
To perform a manual update using Symantec LiveUpdate, users should:
Access LiveUpdate in the product
Run LiveUpdate until all available updates are downloaded and installed
Symantec is not aware of exploitation of or adverse customer impact from this
issue.
Best Practices
As part of normal best practices, Symantec strongly recommends the following:
Restrict access to administrative or management systems to authorized
privileged users.
Restrict remote access, if required, to trusted/authorized systems only.
Run under the principle of least privilege where possible to limit the impact
of potential exploit.
Keep all operating systems and applications current with vendor patches.
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 to both inbound and outbound threats.
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.
