Date Discovered February 14, 2017
Description Adobe Flash Player is prone to multiple heap-based buffer overflow vulnerabilities because it fails to properly bounds check user-supplied data before copying it into an insufficiently sized buffer.
Attackers can exploit these issues to execute arbitrary code in the context of the application. Failed attacks may cause a denial-of-service condition.
Run all software as a nonprivileged user with minimal access rights. To reduce the impact of latent vulnerabilities, run the application with the minimal amount of privileges required for functionality.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity including unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Do not accept or execute files from untrusted or unknown sources. To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.
Do not follow links provided by unknown or untrusted sources.
To reduce the likelihood of attacks, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.
Updates are available. Please see the references or vendor advisory for more information.
