The rb_get_path_check function in file.c in Ruby 1.9.3 before patchlevel 286 and Ruby 2.0.0 before r37163 allows context-dependent attackers to create files in unexpected locations or with unexpected names via a NUL byte in a file path.

Security readout for executives and security teams

This is an old Ruby runtime flaw where a specially crafted file path containing a NUL byte could cause Ruby to create a file somewhere unexpected or under an unexpected name. Business risk depends on whether applications using affected Ruby versions accept attacker-controlled paths for file creation. Exposure is most likely in legacy applications or systems still running affected Ruby 1.9.3 or early Ruby 2.0.0 builds, especially where user input can influence file paths or file creation. Treat this as a legacy runtime hygiene issue with targeted urgency. Prioritize internet-facing or multi-user applications that still run affected Ruby versions and process user-supplied file paths. Mitigation focus: Upgrade Ruby 1.9.3 to patchlevel 286 or later.; Upgrade Ruby 2.0.0 to revision r37163 or later.; Apply Fedora, Red Hat, or other OS vendor Ruby security updates where applicable..
