Cisco Systems revealed in a security bulletin Wednesday that it “inadvertently” shipped in-house exploit code that was used in security tests of scripts as part of its TelePresence Video Communication Server and Expressway Series software. The code exploits the Dirty Cow vulnerability (CVE-2016-5195), a well-known privilege escalation vulnerability in the Linux Kernel, which came to light in 2016.
The code was used internally by Cisco in validation scripts to be included in shippin...

LKRG: Linux to Get a Loadable Kernel Module for Runtime Integrity Checking

Members of the open source community are working on a new security-focused project for the Linux kernel. Named Linux Kernel Runtime Guard (LKRG), this is a loadable kernel module that will perform runtime integrity checking of the Linux kernel.
Its purpose is to detect exploitation attempts for known and unknwon security vulnerabilities against the Linux kernel and attempt to block attacks.
LKRG will also detect privilege escalation for running processes, and kill the running process...

Dirty COW redux: Linux devs patch botched patch for 2016 mess

Dirty COW is a privilege escalation vulnerability in Linux's “copy-on-write” mechanism, first documented in October 2016 and affecting both Linux and Android systems.

The Dirty Cow vulnerability lived in Linux for close to a decade, and while it was patched in October in the kernel and in Linux distributions, Android users had to wait for more than a month for their fix.
Today, Google included a patch for CVE-2016-5195 in the monthly Android Security Bulletin, the final one for 2016. The Dirty Cow patch is one of 11 critical vulnerabilities, all of which are in the Dec. 5 patch level; a separate Dec. 1 patch level was also released today that included p...

Google’s November Android Security Bulletin, released Monday, patched 15 critical vulnerabilities and addressed 85 CVEs overall. But conspicuously absent is a fix for the Linux race condition vulnerability known as Dirty Cow (Copy-on-Write) that also impacts Android.
While Google didn’t issue an official fix for the Dirty Cow vulnerability (CVE-2016-5195), it did release “supplemental” firmware updates for its Nexus and Pixel handsets. According to Michael Cherny, head of security...

Serious Dirty Cow Linux Vulnerability Under Attack
Threatpost • Michael Mimoso • 21 Oct 2016

A nine-year-old Linux vulnerability that affects most of the major distributions has been recently used in public attacks. The flaw, nicknamed Dirty Cow because it lives in the copy-on-write (COW) feature in Linux, is worrisome because it can give a local attacker root privileges.
While the Linux kernel was patched on Wednesday, the major distributions are preparing patches. Red Hat, for example, told Threatpost that it has a temporary mitigation available through the kpatch dynamic kernel...
