A vulnerability classified as critical was found in Intel 5520 Chipset (unknown version). Affected by this vulnerability is an unknown code block of the component Trusted Execution. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
Buffer overflow in Intel Trusted Execution Technology (TXT) SINIT Authenticated Code Modules (ACM) in Intel Q67 Express, C202, C204, C206 Chipsets, and Mobile Intel QM67, and QS67 Chipset before 2nd_gen_i5_i7_SINIT_51.BIN Express; Intel Q57, 3450 Chipsets and Mobile Intel QM57 and QS57 Express Chipset before i5_i7_DUAL_SINIT_51.BIN and i7_QUAD_SINIT_51.BIN; Mobile Intel GM45, GS45, and PM45 Express Chipset before GM45_GS45_PM45_SINIT_51.BIN; Intel Q35 Express Chipsets before Q35_SINIT_51.BIN; and Intel 5520, 5500, X58, and 7500 Chipsets before SINIT ACM 1.1 allows local users to bypass the Trusted Execution Technology protection mechanism and perform other unspecified SINIT ACM functions via unspecified vectors.
The weakness was presented 09/15/2012 by Rafal Wojtczuk with Invisible Things Lab (Website). It is possible to read the advisory at osvdb.org.
