Description
An information disclosure vulnerability exists when the Windows Client Server Run-Time Subsystem (CSRSS) fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application. The update addresses the vulnerability by correcting how the Windows CSRSS handles objects in memory.
