Description |
A remote overflow exists in Microsoft Exchange Server. The 'SvrAppendReceivedChunk()' function in the 'xlsasink.dll' library fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted 'X-LINK2STATE' extended verb request, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
