Microsoft put forth a long list of security updates to cover 79 vulnerabilities, 19 listed as critical, which included four connected to a Microarchitectural Data Sampling (aka ZombieLoad) vulnerability in Intel processors in its May Patch Tuesday release.
While CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091 grabbed the headlines yesterday, Microsoft also patched CVE-2019-0863 which has been spotted in the wild. This is a Windows Error Reporting that incorrectly handles certain files and, when exploited, could lead to the execution of code in kernel mode, providing full administrative control over the system, noted Tripwire.
“The elevation of privilege vulnerability exists in the way Windows Error Reporting handles files. The attack would allow a threat actor to gain kernel mode access to the system. The attacker would need to gain unprivileged execution on the victim’s system first, but that would not be a significant barrier,” said Chris Goettl, Ivanti’s director of product management, security.
