Subject: NULL pointer dereference in XawAsciiSinkInitialize

|
||||
The function XawAsciiSinkInitialize is prone to a NULL pointer
|
||||
dereference if no font is available.
|
||||
|
||||
Even though a specific check for a NULL font exists, it is called
|
||||
after GetGC(), which in turn would trigger the NPE in such a case.
|
||||
|
||||
Spotted by calling xmessage on a system with an incomplete x font setup:
|
||||
|
||||
$ xmessage -b text
|
||||
Warning: Unable to load any usable ISO8859 font
|
||||
Segmentation fault

||||
