DESCRIPTION:
Multiple vulnerabilities have been reported in Microsoft Windows,
which can be exploited by malicious, local users to gain escalated
privileges.
1) An error in the "AllocConsole()" function within the Client/Server
Run-time Subsystem (CSRSS) when multiple console objects are
associated with a process can be exploited to cause a new process to
obtain an orphaned object after the original process terminates.
2) An input validation error in the "SrvSetConsoleLocalEUDC()"
function within the Client/Server Run-time Subsystem (CSRSS) can be
exploited to write certain data into a NULL page.
3) An array-indexing error in the "SrvSetConsoleNumberOfCommand()"
function within the Client/Server Run-time Subsystem (CSRSS) can be
exploited to read data from certain kernel memory locations.
4) An integer overflow error in the "SrvWriteConsoleOutput()"
function within the Client/Server Run-time Subsystem (CSRSS) can be
exploited to corrupt memory.
5) An integer overflow error in the "SrvWriteConsoleOutputString()"
function within the Client/Server Run-time Subsystem (CSRSS) can be
exploited to corrupt memory.
