CVE-2021-21779

Name of the Vulnerable Software and Affected Versions WebKitGTK version 2.30.4

Description A use-after-free vulnerability exists in the way Webkit’s GraphicsContext handles certain events. This can lead to a potential information leak and further memory corruption when a victim visits a specially crafted web page. The vulnerability can be exploited by a remote attacker to access confidential data, compromise data integrity, and cause a denial of service.

Recommendations For WebKitGTK version 2.30.4, update to a version with improved memory management to address the use-after-free issue. As a temporary workaround, consider restricting access to potentially malicious web pages to minimize the risk of exploitation.
