The following commands cause busybox to segfault on musl-based systems. $ install -D a / $ install -D a /b $ install -D a /b/
This happens because the code in https://git.busybox.net/busybox/tree/coreutils/install.c?h=1_25_1#n196 passes the result of dirname() to bb_make_directory() which modifies its contents. For paths of the above forms, musl's dirname returns a string literal "/" which shouldn't be modified. See http://git.musl-libc.org/cgit/musl/tree/src/misc/dirname.c There are a few other occurrences of the code shown above, but I've not checked to see if they could be made to segfault. _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
