virt: guest to host DoS by triggering an infinite loop in microcode via #AC exception

It was found that the x86 ISA Instruction Set Architecture is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way sequential delivering of benign exceptions such as AC alignment check exception is handled. A privileg...

RHEL 7 : kernel-rt (RHSA-2015:1565)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1565 advisory. - kernel: netfilter connection tracking extensions denial of service CVE-2014-9715 - kernel: execution in the early microcode loader...

Scientific Linux Security Update : kernel on SL7.x x86_64 (20150805)

An integer overflow flaw was found in the way the Linux kernel's netfilter connection tracking implementation loaded extensions. An attacker on a local network could potentially send a sequence of specially crafted packets that would initiate the loading of a large number of extensions, causing t...

kernel: execution in the early microcode loader

A stack-based buffer overflow flaw was found in the Linux kernel's early load microcode functionality. On a system with UEFI Secure Boot enabled, a local, privileged user could use this flaw to increase their privileges to the kernel ring0 level, bypassing intended restrictions in place...
