The February 2022 Security Update Review
It’s the second patch Tuesday of 2022, which means the latest security updates from Adobe and Microsoft are here. Take a break from your regularly scheduled activities and join us as we review the details of their latest security offerings.

Adobe Patches for February 2022

For February, Adobe released five bulletins addressing 17 CVEs in Adobe Illustrator, Creative Cloud Desktop, After Effects, Photoshop, and Rush. Two of these 17 were reported by ZDI Vulnerability Researcher Mat Powell. The update for Illustrator fixes a total of 13 bugs, the most severe of which could allow arbitrary code execution through either a buffer overflow or an Out-Of-Bounds (OOB) Write. The patch for Creative Cloud Desktop also fixes a single, Critical-rated code execution bug.

The theme of Critical-rated code execution bugs continues with the fix for After Effects. This patch addresses an OOB write bug that exists within the parsing of 3GP files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated structure. The final Critical-rated patch from Adobe this month fixes a buffer overflow in Photoshop that could allow code execution.

The only Moderate-rated patch this month is the update for Premiere Rush. This patch fixes a bug that exists within the parsing of JPEG images. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.

None of the bugs fixed by Adobe this month are listed as publicly known or under active attack at the time of release.

Microsoft Patches for February 2022

For February, Microsoft released 51 new patches addressing CVEs in Microsoft Windows and Windows Components, Azure Data Explorer, Kestrel Web Server, Microsoft Edge (Chromium-based), Windows Codecs Library, Microsoft Dynamics, Microsoft Dynamics GP, Microsoft Office and Office Components, Windows Hyper-V Server, SQL Server, Visual Studio Code, and Microsoft Teams. A total of five of these bugs came through the ZDI program. This is in addition to the 19 CVEs patched by Microsoft Edge (Chromium-based) earlier this month, which brings the February total to 70 CVEs.

This volume is in line with February releases from previous years, which (apart from 2020) tend to be around 50 CVEs. What’s more curious about this release is the complete lack of Critical-rated patches. Of the patches released today, 50 are rated Important and one is rated Moderate in severity. It may have happened before, but I can’t find an example of a monthly release from Microsoft that doesn’t include at least one Critical-rated patch. It certainly hasn’t happened in recent memory. Interestingly, Microsoft has chosen to provide some additional explanations of CVSS ratings in this month’s release, but there are still many details about the bugs themselves that are left obscured.

None of the bugs are listed as under active exploit this month, while one is listed as publicly known at the time of release. Last month, Microsoft also initially listed the release as having no active attacks only to revise CVE-2022-21882 two days post release to indicate “Microsoft was aware of limited, targeted attacks that attempt to exploit this vulnerability.” We’ll update this blog should they change their mind this month as well.
