A tumultuous, titanic Patch Tuesday as Microsoft makes some changes

April 10, 2024

Several months of relative calm are over for Windows administrators, as Microsoft on Tuesday released 147 patches affecting ten product families. Windows takes the lion’s share of patches with 90, with 38 for SQL Server (including ten shared with Visual Studio). The rest are spread among .NET, 365, Azure, Defender for IoT, Office, Outlook, and SharePoint. There are three critical-severity issues, all affecting Defender for IoT.

At patch time, three issues, all important-severity faults affecting Windows, are known to be under active exploit in the wild. One (CVE-2024-26234, a driver-related issue reported to Microsoft by Sophos) is publicly disclosed, as we’ll discuss below. Eleven more important-severity vulnerabilities in Windows are by the company’s estimation more likely to be exploited in the next 30 days. Six of the issues addressed are amenable to detection by Sophos protections, and we include information on those in a table below.

In addition to these patches, the release includes advisory information on five patches related to the Edge browser and five from Intel, Lenovo, and Red Hat; the regularly scheduled servicing stack updates are also included in advisory material this month. We don’t include advisories in the CVE counts and graphics below, but we provide information on all of them 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: 147
Total Edge / Chrome advisory issues covered in update: 5
Total non-Edge, non-Microsoft advisory issues overed in update: 5
Publicly disclosed: 1
Currently exploited: 3

Figure 1: RCEs came roaring to the forefront this month, but Security Feature Bypass makes a formidable showing (more on that in a bit)

Products

Windows: 90
SQL Server: 38 (including 10 shared with Visual Studio)
Visual Studio: 11 (including 10 shared with SQL Server and one shared with .NET)
Azure: 9
Defender for IoT: 6
.NET: 1 (shared with Visual Studio)
365: 1 (shared with Office)
Office: 1 (shared with 365)
Outlook: 1
SharePoint: 1

Figure 2: Windows accounts for just under two-thirds of the April 2024 patches, with nine other product families also in the mix (but five of those receiving just one patch)

Notable April updates and themes

In addition to the issues discussed above, a few specific items merit attention.

Startup Issues Stack Up

Secure Boot Security Feature Bypass Vulnerability – 24 patches
BitLocker Security Feature Bypass Vulnerability – 1 patch
Lenovo: CVE-2024-23593 Zero Out Boot Manager and drop to UEFI Shell – 1 patch
Lenovo: CVE-2024-23594 Stack Buffer Overflow in LenovoBT.efi – 1 patch

Secure Boot and BitLocker are having an interesting month. All 25 Microsoft patches are important-severity issues. Microsoft says that none of them are currently under active exploitation and that they believe exploitation is less likely in the 30 days after release. The two issues from Lenovo are likewise related to boot processes, are characterized by Microsoft as important-severity Security Feature Bypass faults and are thought to be less likely to be exploited within the next 30 days. (It should be noted that Microsoft mentions the Lenovo releases simply as advisory information.)

CVE-2024-26234 – Proxy Driver Spoofing Vulnerability

As mentioned above, back in December, Sophos X-Ops opened an investigation of a suspicious-looking executable that claimed to be signed by a valid Microsoft Hardware Publisher Certificate. You can read about what happened next in our writeup of what we discovered. For Microsoft’s part, the company has added the relevant files to its rolling revocation list, which is updated in this patch cycle under this CVE. It is the sole issue this month that is considered to be publicly disclosed.

A Tough Month for SQL Server

Microsoft ODBC Driver for SQL Server Remote Code Execution Vulnerability – 13 patches
Microsoft OLE DB Driver for SQL Server Remote Code Execution Vulnerability – 24 patches
Microsoft WDAC OLE DB Provider for SQL Server Remote Code Execution Vulnerability – 3 patches
Microsoft WDAC SQL Server ODBC Driver Remote Code Execution Vulnerability – 1 patch

These 41 patches are all important-severity issues with CVE numbers likely assigned from Microsoft’s CAN block (almost all of them are sequential, which usually indicates that they were drawn from the same block at about the same time). Microsoft says that none of them are currently under active exploitation and that they believe exploitation is less likely in the 30 days after release.

Figure 3: Security Feature Bypass leaps to third place in the cumulative patch totals for 2024, though RCE still leads the pack

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.

Appendix A: Vulnerability Impact and Severity

This is a list of April patches sorted by impact, then sub-sorted by severity. Each list is further arranged by CVE. In an effort to keep our readers informed, we also provide CVSS base and temp scores as those become available, since those may differ from Microsoft’s self-assessments.
