Title: Microsoft fixes more than 70 vulnerabilities as part of May Patch Tuesday

Description: Microsoft returned to its normal monthly patching volume in May, disclosing and fixing 74 vulnerabilities as part of the company’s latest security update. This month’s Patch Tuesday includes seven critical vulnerabilities after Microsoft disclosed more than 140 security issues in April. The point-to-point tunneling feature in Windows contains two of the most serious vulnerabilities that could allow an attacker to execute remote code on a targeted RAS server machine. While CVE-2022-21972 and CVE-2022-23270 are rated “critical,” Microsoft stated the attack complexity is high since an adversary needs to win a race condition, making it less likely an attacker could exploit these issues. CVE-2022-26931 and CVE-2022-26923 are elevation of privilege vulnerabilities in Windows Kerberos and Windows Active Directory, respectively. They both are considered critical, though CVE-2022-26931 is considered less likely to be exploited because it has a higher attack complexity.
