CVE-2020-12612

An issue was discovered in BeyondTrust Privilege Management for Windows through 5.6. When specifying a program to elevate, it can typically be found within the Program Files x86 folder and therefore uses the %ProgramFilesx86% environment variable. However, when this same policy gets pushed to a...

kernel: perf/x86/amd: fix potential integer overflow on shift of a int

A flaw was found in the support for AMD processors in the Linux kernel. An improper left shift of a 32-bit integer can cause an integer overflow, possibly impacting system stability and resulting in a denial of service...

Important: kernel-livepatch-4.14.320-243.544

Issue Overview: A use-after-free vulnerability in the Linux kernel's net/sched: clsroute component can be exploited to achieve local privilege escalation. When route4change is called on an existing filter, the whole tcfresult struct is always copied into the new instance of the filter. This cause...
