GHSA-8W8G-WQ8H-FQ33 Dulwich: Symlink write-through in checkout(paths=[]) via raw os.open bypasses all symlink protections

Summary Dulwich's porcelain.checkoutpaths=... code path writes files using raw os.openfilepath, OWRONLY|OCREAT|OTRUNC, mode followed by f.writeobj.data. This code path does NOT call buildfilefromblob at all, completely bypassing any symlink protections including the unreleased d09f8af fix. os.ope...

UNIX Symbolic Link (Symlink) Following

Overview Affected versions of this package are vulnerable to UNIX Symbolic Link Symlink Following via the paths= branch of porcelain.checkout in dulwich, which wrote file content using a raw os.openfilepath, OWRONLY|OCREAT|OTRUNC call that follows existing symlinks at the target path. An attacker...
