Uninitialized read in gdImageCreateFromXbm

[MEDIUM] Uninitialized read in gdImageCreateFromXbm
Uninitialized read in gdImageCreateFromXbm
This bug is present in gdImageCreateFromXbm method of ext/gd/libgd/gd_xbm.c file.
This method contains below mentioned lines.
```c
...
unsigned int b;
...
sscanf(h, "%x", &b);
for (bit = 1; bit <= max_bit; bit = bit << 1) {
gdImageSetPixel(im, x++, y, (b & bit) ? 1 : 0);
...
```
So when sscanf method is not able to read a hex value, "b" variable will contain uninitialized data.
