Microsoft June 2024 patch fixes 51 vulnerabilities, including Message Queueing critical flaw
Take action: Time for the Microsoft patch. This time Windows operating system is high priority - especially with the critical flaw of MSMQ service. Either patch ASAP (preferred) or disable MSMQ and block access to port TCP 1801. Then focus on Microsoft Office and review the rest for regular patching.

Microsoft has released the June 2024 Patch Tuesday updates, addressing a total of 51 security vulnerabilities, including 18 remote code execution (RCE) flaws and one publicly disclosed zero-day vulnerability.
The most critical vulnerability in this update is a remote code execution flaw in Microsoft Message Queuing (MSMQ), tracked as CVE-2024-30080 (CVSS score 9.8). This vulnerability allows remote attackers to send specially crafted MSMQ packets to take over affected servers. It is remotely exploitable, requires no privileges, has low attack complexity, and needs no user interaction. Affected systems include all versions of Windows starting from Windows Server 2008 and Windows 10.
This month’s Patch Tuesday also includes a fix for a publicly disclosed zero-day vulnerability known as the 'Keytrap' attack in the DNS protocol, tracked as CVE-2023-50868 (CVSS score 7.5). This vulnerability affects DNSSEC validation, allowing attackers to exhaust CPU resources on a resolver, causing a denial of service. It has been addressed in various DNS implementations such as BIND, PowerDNS, Unbound, Knot Resolver, and Dnsmasq.
The vulnerabilities fixed in this update span multiple categories:
- 25 Elevation of Privilege Vulnerabilities
- 18 Remote Code Execution Vulnerabilities
- 3 Information Disclosure Vulnerabilities
- 5 Denial of Service Vulnerabilities
Apart from the critical MSMQ vulnerability, other notable fixes include multiple RCE vulnerabilities in Microsoft Office, Outlook, and several Windows components, such as:
- CVE-2024-30103 (CVSS score 8.8): RCE vulnerability in Microsoft Outlook, exploitable via the Preview Pane.
- CVE-2024-30089 (CVSS score 7.8): Privilege escalation vulnerability in Microsoft Streaming Services.
- CVE-2024-30085 (CVSS score 7.8): Privilege escalation bug in Windows Cloud Files Mini Filter Driver.
- CVE-2024-30099 (CVSS score 7.0): Elevation-of-privilege vulnerability in Windows Kernel Driver.
Microsoft urges users and administrators to apply these patches promptly to mitigate potential risks. Systems should be checked to ensure MSMQ service is not running on TCP port 1801 if not needed.
