This must be coming from xcb_cursor_load_cursor(): <a href="http://cgit.freedesktop.org/xcb/util-cursor/tree/cursor/load_cursor.c#n227">http://cgit.freedesktop.org/xcb/util-cursor/tree/cursor/load_cursor.c#n227</a> So something is missing a 0-check somewhere. Thinking "how does libXcursor handle this", I found the following. It's the only 0-check I saw and no idea if this is the right one: <a href="http://cgit.freedesktop.org/xorg/lib/libXcursor/tree/src/file.c#n425">http://cgit.freedesktop.org/xorg/lib/libXcursor/tree/src/file.c#n425</a> while xcb-util-cursor doesn't do anything equivalent to this: <a href="http://cgit.freedesktop.org/xcb/util-cursor/tree/cursor/parse_cursor_file.c#n148">http://cgit.freedesktop.org/xcb/util-cursor/tree/cursor/parse_cursor_file.c#n148</a> Since I have a hard time imagining that such a broken cursor file could be laying around anywhere, I hope someone can figure out where this broken data is coming from. Perhaps the fix is as easy as checking for too small (and also for too large? libXcursor does that) width/height in parse_cursor_file().</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
