[Xtightvnc] Segfault #58

Open fzg opened 9 years ago

fzg commented 9 years ago

Hey. I'm no X11 guru, so this is possibly an issue with Xtightvnc. Is it?

Program received signal SIGSEGV, Segmentation fault. 0x00007ffff7bd7e8f in _xdo_populate_charcode_map (xdo=0x61ba80) at xdo.c:1304 $1 = (XkbDescPtr) 0x0 $2 = 8

(gdb) where

0 0x00007ffff7bd7e8f in _xdo_populate_charcode_map (xdo=0x61ba80) at xdo.c:1304

1 xdo_new_with_opened_display (xdpy=, display=, close_display_when_freed=close_display_when_freed@entry=1) at xdo.c:133

4 0x0000000000403724 in xdotool_main (argc=4, argv=0x7fffffffe668) at xdotool.c:316

So we got an unhandled NULL coming from XkbGetMap() :-(

Xvnc version TightVNC-1.3.9 Linux xxxx 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u3 x86_64 GNU/Linux xdotool/libxd built minutes ago from HEAD.

Definitely sounds like a bug. I'll try to reproduce with Xtightvnc next time I get the chance.

Jumping in this old bug... Got the issue, trace it to XkbGetMap in _xdo_populate_charcode_map returning a null pointer. I added a if that skips the for loops, it stops the crash, but things like Ctrl+Shift+T don't work. I can see a t, show up on the console though. At this point I'm stump.
