[PATCH] fix buffer overrun in pdump_load() 17 years, 8 months

Nix

The initial problem was easy to describe: starting XEmacs with absolute paths was broken (at least it is if you use a separate .dmp file, which I'm constrained to right now because I'm using the new GC.) loki 1686 /usr/packages/xemacs/i686-loki% which xemacs /usr/bin/xemacs loki 1687 /usr/packages/xemacs/i686-loki% xemacs -vanilla -batch -eval '(message "foo")' foo loki 1685 /usr/packages/xemacs/i686-loki% /usr/bin/xemacs -vanilla -batch -eval '(message "foo")' temacs can only be run in -… [View More]batch mode. strace and valgrind (and a bit of gdb) pinpoint the cause: loki 1688 /usr/packages/xemacs/i686-loki% strace -e open /usr/bin/xemacs -vanilla -batch -eval '(message "foo")' [...] open("/lib/libpthread.so.0", O_RDONLY) = 3 open("", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory) open("", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory) open("", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory) open("/etc/fonts/fonts.conf", O_RDONLY|O_LARGEFILE) = 3 [...] ==29209== Syscall param open(filename) points to unaddressable byte(s) ==29209== at 0x4D873272: open64 (in /lib/libc-2.4.so) ==29209== Address 0xBEBA0070 is not stack'd, malloc'd or (recently) free'd If you're unlucky, that "" turns into an -EFAULT, and if you're *really* unlucky, you get a segfault. This is happening because in src/dumper.c:pdump_load(), exe_path is being sized as (if XEmacs is invoked with an absolute path) one byte longer than the length of the directory component of the name, or (if XEmacs is invoked with a relative path) ten bytes longer than the larger of the name and PATH variable... ... and then pdump_load() calls pdump_file_try(), which proceeds to sprintf() things on the end of it, like "-21.5-b27-453712b7.dmp". Oops, there's no room for that. Instant buffer overrun, and because that structure is alloca()ed a lot of the time, instant stack overrun as well, which if you're unlucky blows away a pile of variables, invalidates `exe_path', et seq ad nauseam. (Probably nobody's noticed this because most of the time XEmacs is invoked without an absolute path, and most people have a PATH that is much longer than five characters. I don't know what the ten bytes of slop are for: it's not even long enough for `-21.4.16.dmp'...) I've `fixed' this by moving from incorrect dynamic allocation to arguably inefficient-but-who-cares static allocation: it's way too much work to realloc() this string, and it's also way too much work to determine the maximum possible length of that string (plus it's brittle; the next time someone changes the filename construction method, *boom*). This necessitated a tiny fix to text.h before PATH_MAX_EXTERNAL could be used on non-Windows systems at all... You may want to fix the fix if using PATH_MAX_{INTERNAL,EXTERNAL} is really as bad as all that. (This patch is against CVS HEAD.) 2006-10-26 Nix <nix(a)esperi.org.uk> * dumper.c (pdump_load): Statically allocate a large enough exe_path for all conceivable uses.

[PATCH (pkgs)] Small AUCTeX tweak 17 years, 11 months

Jerry James

PATCH packages As David Kastrup said on xemacs-beta, using rawfile IS the right thing to do here. I suggest this patch as a stopgap measure until we can figure out how to import the latest version of AUCTeX. This incidentally fixes the building of HISTORY. xemacs-packages/auctex/ChangeLog addition: 2006-08-03 Jerry James <james(a)xemacs.org> * Makefile (EXTRA_SOURCES): Add HISTORY. * Makefile (RUN_MAKEINFO_INDIVIDUAL): Build plain text files with -D rawfile. * Makefile (… [View More]

[PATCH 21.5] gnuclient buffer overflow fixes 18 years, 4 months

[PATCH] Make locate startup files work in 21.5 18 years, 5 months

Malcolm Purvis

This is the second of my locale specific patches. The locale package provides for custom startup screens. In 21.4 they are fetched by $LANG (eg 'fr') but for 21.5 they are accessed via current-language-environment (eg 'French'). This patch installed these files in two directories so that they can be found by 21.5 and 21.4. I thought about using a symlink to alias the directory but that wouldn't work under Windows. mule-packages/locale/ChangeLog addition: 2006-10-22 Malcolm Purvis <… [View More]
