Name of the Vulnerable Software and Affected Versions Firefox versions prior to 68

Description The issue is related to the incorrect handling of certain Unicode characters during web content parsing, which can lead to the execution of malicious code and evade cross-site scripting (XSS) filtering. This allows a remote attacker to impact data integrity.
