Symantec Endpoint Protection AvHostPlugin Out-of-Bounds Read Information Disclosure Vulnerability

This vulnerability allows local attackers to disclose sensitive information on affected installations of Symantec Endpoint Protection Manager. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the AvHostPlugin.dll. The issue results from the lack of proper validation of user-supplied data, which can result in a read before the start of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM.
