CVE-2021-29962

Name of the Vulnerable Software and Affected Versions Firefox for Android versions prior to 89

Description The issue is related to the incorrect cleanup or release of resources, which can be exploited by an attacker to cause a denial of service. This can happen when a website opens too many popups, causing Firefox for Android to become unstable and hard to recover. The estimated number of potentially affected devices is not specified.

Recommendations For Firefox for Android versions prior to 89, update to version 89 or later to resolve the issue. As a temporary workaround, consider restricting the number of popups that can be opened by a website to minimize the risk of exploitation.
