CVE:CVE-2011-5174
CNNVD:CNNVD-201209-338
Intel Trusted Execution Technology（TXT，英特尔可信任执行技术）是美国英特尔（Intel）公司酷睿2双核处理器中的一项硬件延伸技术，主要用于保护虚拟化计算环境中的数据，可避免受到间谍软件攻击、病毒入侵等威胁。
Intel多个版本中的Intel Trusted Execution Technology (TXT) SINIT Authenticated Code Modules (ACM)中存在缓冲区溢出漏洞。本地攻击者可利用该漏洞通过未明向量绕过Trusted Execution Technology保护机制，并执行其他未明SINIT ACM函数。以下版本受到影响：Intel Q67 Express、C202、C204、C206 Chipsets，Mobile Intel QM67、QS67 Chipset 2nd_gen_i5_i7_SINIT_51.BIN Express之前的版本Intel Q57，3450 Chipsets和Mobile Intel QM57、QS57 Express Chipset i5_i7_DUAL_SINIT_51.BIN and i7_QUAD_SINIT_51.BIN之前的版本、Mobile Intel GM45, GS45,PM45 Express Chipset GM45_GS45_PM45_SINIT_51.BIN之前的版本、Intel Q35 Express Chipsets Q35_SINIT_51.BIN之前的版本、Intel 5520, 5500, X58、7500 Chipsets before SINIT ACM 1.1之前的版本
