CVE-2014-0222

Integer overflow in the qcowopen function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service crash via a large L2 table in a QCOW version 1 image...

Qemu: qcow1: validate L2 table size to avoid integer overflows

An integer overflow flaw was found in the QEMU block driver for QCOW version 1 disk images. A user able to alter the QEMU disk image files loaded by a guest could use this flaw to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with...

[oss-security] CVE-2014-0222 Qemu: qcow1: Validate L2 table size

Hello, 'CVE-2014-0222' has been assigned to this issue. Too large L2 table sizes cause unbounded allocations. Images actually created by qemu-img only have 512 byte or 4k L2 tables. To keep things consistent with cluster sizes, allow ranges between 512 bytes and 64k in fact, down to 1 entry = 8...

Intel CORE 2处理器多个本地拒绝服务漏洞

Intel CORE 2是非常流行的双核处理器。 CORE 2处理器中存在多个拒绝服务漏洞： 如果温度达到了无效的温度，则即使已经超过了设置的阀值，CPU仍不会生成Thermal中断； 在执行一系列REP存储指令期间，存储可能会在完成指令之前便试图分派内存，导致处理器锁定和/或系统挂起； 如果一个逻辑处理器写入非脏页面（dirty page），另一个逻辑处理器写入相同的非脏页面或在相关的页面表项中明确的设置脏位，则内部处理器行为的复杂交互会导致不可预测的系统行为并挂起； 如果从Core 1请求数据导致L1缓存丢失，就会将请求发送给L2缓存。如果这个请求遇到了Core...
