WebKit Cross Site Scripting and Multiple Memory Corruption Vulnerabilities

Risk

High

Date Discovered

October 28, 2019

Description

WebKit is prone to a cross-site scripting vulnerability and multiple memory-corruption vulnerabilities. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site or execute arbitrary code in the context of the affected system. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Failed exploit attempts will likely cause a denial-of-service condition.

Recommendations

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. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from a successful exploit.

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.

Implement multiple redundant layers of security.
As an added precaution, deploy memory-protection schemes (such as nonexecutable stack/heap configuration and randomly mapped memory segments). This may complicate exploits of memory-corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
