- Details
-
When sed is invoked with both -i (in-place edit) and --follow-symlinks, the function opennextfile() performs two separate, non-atomic filesystem operations on the same path:
- resolves symlink to its target and stores the resolved path for determining when output is written,
- opens the original symlink path (not the resolved one) to read the file. Between these two calls there is a race window. If an attacker atomically replaces the symlink with a different target during that window, sed will: read content from the new (attacker-chosen) symlink target and write the processed result to the path recorded in step 1. This can lead to arbitrary file overwrite with attacker-controlled content in the context of the sed process.
This issue was fixed in version 4.10.
