CVE-2023-23946
Git, a revision control system, is vulnerable to path traversal prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.14%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Git, a revision control system, is vulnerable to path traversal prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8. By feeding a crafted input to `git apply`, a path outside the working tree can be overwritten as the user who is running `git apply`. A fix has been prepared and will appear in v2.39.2, v2.38.4, v2.37.6, v2.36.5, v2.35.7, v2.34.7, v2.33.7, v2.32.6, v2.31.7, and v2.30.8. As a workaround, use `git apply --stat` to inspect a patch before applying; avoid applying one that creates a symbolic link and then creates a file beyond the symbolic link.
