https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236870 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=3D203232&action= =3Dedit libarchive directory traversal patch libarchive-based utilities, notably including tar(1), fail if told to trave= rse "." 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 directo= ry, which is an obviously wrong thing to do. Attached patch (against 12-stable) fixes this and includes a test case. --=20 You are receiving this mail because: You are the assignee for the bug.=
