| Description |
There is an open race window when writing output in the following utilities in GNU binutils: ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink. The issue was fixed in binutils version 2.36, but subsequently the fix was partly reverted in version 2.36.1 because it was causing issues with the file archiver "ar". |
