| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, I've spent the half night staring at the devilish my_getpwuid and my_getgrgid functions trying to find out a way to avoid actual and future potential buffer overflow problems without breaking existing code. Finally I've found a not intrusive way to do this that surely doesn't break existing code and fixes a couple of problems too. The attached patch: 1) changes the behaviour of my_getpwuid and my_getgrgid to avoid potetntial buffer overflows 2) fixes all occurences of this function calls in tar.c , id.c , ls.c, whoami.c, logger.c, libbb.h. 3) The behaviour of tar, ls and logger is unchanged. 4) The behavior of ps with somewhat longer usernames messing up output is fixed. 5) The only bigger change was the increasing of size of the buffers in id.c to avoid false negatives (unknown user: xxxxxx) with usernames longer than 8 chars. The value i used ( 32 chars ) was taken from the tar header ( see gname and uname). Maybe this buffers can be reduced a bit ( to 16 or whatever ), this is up to you. 6) The increase of size of the binary is not so dramatic: size busybox text data bss dec hex filename 239568 2300 36816 278684 4409c busybox size busybox_fixed text data bss dec hex filename 239616 2300 36816 278732 440cc busybox 7) The behaviour of whoami changed: actually it prints out an username cut down to the size of the buffer. This could be fixed by increasing the size of the buffer as in id.c or avoid the use of my_getpwuid and use getpwuid directly instead. Maybe this colud be also remain unchanged...... Please apply if you think it is ok to do so. The diff applies on today's cvs tarball (2004-08-25). Thanks in advance, Ciao, Tito
* BusyBox has no business hard coding the number of major and minor bits for aEric Andersen2004-07-261-9/+5
| | | | | | | | | dev_t. This is especially important now that the user space concept of a dev_t and the kernel concept of a dev_t are divergant. The only bit of user space allowed to know the number of major and minor bits is include/sys/sysmacros.h (i.e. part of libc). When used with a current C library and a 2.6.x kernel, this fix should allow BusyBox to support wide device major/minor numbers. -Erik

| | | | | | | | | | | Hello, I found and patched 2 more bugs. The first is a misplaced semi-colon. The second one is a buffer overflow. I doubt the buffer overflow is triggered in real life. But you never know what those wily hackers are up to. Thanks, Steve Grubb

| | | | | | | | | | | | | | | | | | | | | | This is a bulk spelling fix patch against busybox-1.00-pre10. If anyone gets a corrupted copy (and cares), let me know and I will make alternate arrangements. Erik - please apply. Authors - please check that I didn't corrupt any meaning. Package importers - see if any of these changes should be passed to the upstream authors. I glossed over lots of sloppy capitalizations, missing apostrophes, mixed American/British spellings, and German-style compound words. What is "pretect redefined for test" in cmdedit.c? Good luck on the 1.00 release! - Larry

* As noted by Thomas Eckert:Eric Andersen2003-07-051-2/+9
| | | | | | | | | | | | | | | | bb-tar "cjf" does not create a valid tbz2-archive -- if fact the result is a plain tar-file (no compression) -- but does not warn about the unrecognized parameter combination "cj" (bb does not have bzip2-compression yet, right?). to fix this I have added an error message stating this does not work. He also reported cosmetic: versose "-v" does not show any output when used with "create" which I have now fixed as well. -Erik
