https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236870 Bug ID: 236870 Summary: libarchive directory traversal gives spurious permission errors Product: Base System Version: 12.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: andrew@tao11.riddles.org.uk Created attachment 203232 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=203232&action=edit libarchive directory traversal patch libarchive-based utilities, notably including tar(1), fail if told to traverse "." if the parent directory is not readable. This is caused by libarchive trying to open ".." at the end of the traverse in order to exit the directory, which is an obviously wrong thing to do. Attached patch (against 12-stable) fixes this and includes a test case. -- You are receiving this mail because: You are the assignee for the bug.
