**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 79.0.3945.79 **Description** The issue is related to type confusion in JavaScript, which can be exploited by a remote attacker to potentially cause heap corruption via a crafted HTML page. This could allow the attacker to gain unauthorized access to confidential data, cause a denial of service, and impact data integrity. **Recommendations** For versions prior to 79.0.3945.79, update to version 79.0.3945.79 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable HTML pages until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Microsoft Edge (affected versions not specified) **Description** The issue is related to errors in handling objects in memory by the ChakraCore JavaScript engine. It could allow a remote attacker to execute arbitrary code using a specially crafted web page. The vulnerability can corrupt memory, enabling an attacker to gain the same user rights as the current user. If the current user has administrative rights, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
