2024’s first Patch Tuesday steps lightly

Credit to Author: Angela Gunn| Date: Tue, 09 Jan 2024 22:03:14 +0000

January isn’t traditionally the lightest month on patch managers’ calendars, so a second month of (relatively) few Microsoft releases is a bit of a treat. On Tuesday the company released 48 CVEs, including 38 for Windows. Eight other product groups or tools are also affected. Of the CVEs addressed, just two are considered Critical in severity by Microsoft; both affect Windows.

At patch time, none of the issues are known to be under exploit in the wild, and none have been publicly disclosed. However, nine of the addressed vulnerabilities in Windows and SharePoint (including one of the Critical-severity CVEs, affecting Kerberos) are by the company’s estimation more likely to be exploited in the next 30 days. Four of those are amenable to detection by Sophos protections, and we include information on those in a table below.

In addition to the 48 patches the release included information on four Chrome CVEs (released last week) that affect Edge, and one MITRE-issued CVE touching the open-source database engine SQLite. (There are no Adobe offerings this month.) We don’t include those issues in the CVE counts and graphics below, but we provide information on everything in an appendix at the end of the article. We are as usual including at the end of this post three other appendices listing all Microsoft’s patches, sorted by severity, by predicted exploitability, and by product family.

By the numbers

  • Total Microsoft CVEs: 48

    Figure 1: You’re reading the labels correctly: Information-disclosure issues outnumber both EoP and RCE bugs in January. Security feature bypass issues – one of them Critical-severity — also make a strong showing

    Products

    • Windows: 38
    • .NET: 5 (including on shared with Visual Studio; one shared with Microsoft Identity Model / NuGet and Visual Studio; and one shared with Azure, SQL Server, and Visual Studio)

    Notable January updates

    In addition to the issues discussed above, a few specific items are worth noting.

    CVE-2024-0057 — .NET, .NET Framework, and Visual Studio Framework Security Feature Bypass Vulnerability
    CVE-2024-20674 — Windows Kerberos Security Feature Bypass Vulnerability

    Of this pair of security feature bypass issues, Microsoft deems only the Kerberos issue to be Critical-class. The CVSS scoring system begs to differ, since the guide to that scoring system requires that scorers consider feasible worst-case scenarios when evaluating bugs in software libraries. Their CVSS base scores are thus 9.1 and 9.0 respectively. In any case, admins are encouraged to prioritize these two patches.

    CVE-2024-20696 – Windows Libarchive Remote Code Execution Vulnerability
    CVE-2024-20697 – Windows Libarchive Remote Code Execution Vulnerability

    The information available on these two identically named Important-class RCEs is scant, but there’s a big clue to their importance in the title: These two issues affect Libarchive, the engine for reading and writing in various compression and archive formats.

    CVE-2024-20666 – BitLocker Security Feature Bypass Vulnerability

    Another security feature bypass, this time in a security feature. This issue stands out for some fairly nuanced requirements around servicing the Safe OS; for most versions of Windows 11 this is now a fully automated process, and those relying on WSUS are automatically updated, but those working in more complex environments are strongly encouraged to check Microsoft’s published guidance for specific instructions. In any case, the attacker requires physical access to the targeted machine.

    CVE-2024-21305 — Hypervisor-Protected Code Integrity (HVCI) Security Feature Bypass Vulnerability

    The CVE with the lowest CVSS base score this month has something in common with the two highest-scoring CVEs: It’s yet another security feature bypass. This one, however, rates a mere 4.4 base score and requires the attacker to have physical access to the targeted machine and to have previously compromised admin credentials. It affects an assortment of Windows client and server versions and, for those still running that hardware, 15 versions of the Surface.

    Sophos protections

     

    As you can every month, if you don’t want to wait for your system to pull down Microsoft’s updates itself, you can download them manually from the Windows Update Catalog website. Run the winver.exe tool to determine which build of Windows 10 or 11 you’re running, then download the Cumulative Update package for your specific system’s architecture and build number.
