CVE-2024-10933

Local file disclosure via slash-bearing readdir names

Published Dec 5, 2024 · Updated Dec 5, 2024

Path traversal in OpenBSD 7.4 before errata 022 and 7.5 before errata 009 allows local users to read files via an untrusted file system. The readdir name validator fails to reject slash characters in directory-entry names, allowing one entry to be interpreted as multiple path components. Reaching the flaw requires low-privileged local access, active user interaction, and a controllable untrusted file system; the published impact is file disclosure only.
