• EPSS: 0.4% probability of exploitation in the next 30 days

Description

Git for Windows is the Windows port of the revision control system Git. Prior to Git for Windows version 2.39.2, by carefully crafting DLL and putting into a subdirectory of a specific name living next to the Git for Windows installer, Windows can be tricked into side-loading said DLL. This potentially allows users with local write access to place malicious payloads in a location where automated upgrades might run the Git for Windows installer with elevation. Version 2.39.2 contains a patch for this issue. Some workarounds are available. Never leave untrusted files in the Downloads folder or its sub-folders before executing the Git for Windows installer, or move the installer into a different directory before executing it.

Affected products

• git-for-windows git: before 2.39.2 — fixed in 2.39.2

How to fix

Upgrade to a fixed version: git-for-windows git 2.39.2. Check the vendor advisory for mitigations.
