New 'Lazy FP State Restore' Vulnerability Found in All Modern Intel CPUs

Hell Yeah! Another security vulnerability has been discovered in Intel chips that affects the processor's speculative execution technology—like Specter and Meltdown—and could potentially be exploited to access sensitive information, including encryption related data. Dubbed Lazy FP State Restore ...

CVE-2018-3665

System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel...

Speculative register leakage from lazy FPU context switching

ISSUE DESCRIPTION x86 has a hardware mechanism for lazy FPU context switching. On a task switch, %cr0.ts Task Switched gets set, and the next instruction to touch floating point state raises an NM No Math, later known as Device Not Available exception. Traditionally, FPU state has been large in...

Debian DSA-4210-1 : xen - security update (Spectre)

This update provides mitigations for the Spectre v4 variant in x86-based micro processors. On Intel CPUs this requires updated microcode which is currently not released publicly but your hardware vendor may have issued an update. For servers with AMD CPUs no microcode update is needed, please ref...

XML External Entities (XXE)

nifi-standard-processors is vulnerable to XML external entities XXE attacks. The vulnerability exists due to the lack of proper default configuration which disables external entities by default, allowing XXE attacks to occur...

Denial Of Service (DoS) Through JMS Deserialization

nifi-jms-processors is vulnerable to denial of service DoS attacks. The vulnerability exists due to the usage of the vulnerable transitive activemq-client library, affected by CVE-2015-5254, which would cause a DoS attack when malicious JMS content is parsed...
