CVE-2019-11091 [MEDIUM] x86/mds: Add MDSUM variant to the MDS documentation
x86/mds: Add MDSUM variant to the MDS documentation
Updated the documentation for a new CVE-2019-11091 Microarchitectural Data
Sampling Uncacheable Memory (MDSUM) which is a variant of
Microarchitectural Data Sampling (MDS). MDS is a family of side channel
attacks on internal buffers in Intel CPUs.
MDSUM is a special case of MSBDS, MFBDS and MLPDS. An uncacheable load from
memory that takes a fault or assist can leave data in a microarchitectural
structure that may later be observed using one of the same methods used by
MSBDS, MFBDS or MLPDS. There are no new code changes expected for MDSUM.
The existing mitigation for MDS applies to MDSUM as well.

[CRITICAL] May 2019 Patch Tuesday - 79 Vulns, 22 Critical, RDP RCE, MDS Attacks, Adobe Vulns | Qualys
This month’s Microsoft Patch Tuesday addresses 79 vulnerabilities with 22 of them labeled as Critical. Of the 22 Critical vulns, 18 are for scripting engines and browsers. The remaining 4 are remote code execution (RCE) in Remote Desktop, DHCP Server, GDI+, and Word. Microsoft also released guidance on the recently disclosed Microarchitectural Data Sampling (MDS) techniques, known as ZombieLoad, Fallout, and RIDL. Adobe’s Patch Tuesday includes patches for vulnerabilities in Flash, Acrobat/Reader (83 vulnerabilities!) and Media Encoder.
UPDATE May 15: Microsoft has also issued Remote Desktop patches for Windows XP and Server 2003.
### Workstation Patches
Scripting Engine, Browser, GDI+, and Word patches should be prioritized for workstation-type devices, meaning any system that is used
