A use after free issue in V8 allows a remote attacker to execute arbitrary code inside a sandbox. This is achieved by convincing a user to perform specific UI gestures while interacting with a crafted HTML page. Use after free is a memory corruption flaw that occurs when an application continues to use a pointer after it has been freed.

This issue allows local attackers to escalate privileges on affected installations. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this issue. The specific flaw exists within the e1000 virtual device. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this issue to escalate privileges and execute arbitrary code in the context of the hypervisor.

This issue allows local attackers to escalate privileges on affected installations. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this issue. The specific flaw exists within the Toolgate component, resulting from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this issue to escalate privileges and execute code in the context of the current user on the host system.

The issue allows remote attackers to execute arbitrary code via a crafted serialized Java object. This object triggers an LDAP query to a third-party server.
