Description Bhavi Dhingra 2015-09-28 09:49:26 UTC
Created attachment 118481 [details]
NULL check added to prevent crash

In libX11/modules/im/ximcp/imDefLkup.c, Line #91,
_XimICOfXICID returns NULL, Assigning: ic = null return value from _XimICOfXICID
Dereferencing a pointer that might be null ic when calling _XimProcICSetEventMask

Hence, adding a NULL check to avoid crash.

X.Org has very few active maintainers and a years long patch backlog.

We also request patches be mailed to xorg-devel for review on the website:

That may not make them go in any faster, but harassing us for you not following
instructions and complaining we've not jumped on it in a few weeks tends to make
us move slower.
