Name of the Vulnerable Software and Affected Versions Microsoft Edge (affected versions not specified)

Description A remote code execution issue exists in the way the Chakra scripting engine handles objects in memory. This could allow an attacker to execute arbitrary code in the context of the current user by hosting a specially crafted website and convincing a user to view it. The attacker could also exploit compromised websites or those that accept user-provided content. 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.
