[E-devel] [PATCH][ETHUMB] Null checks and checks if divisor is not equal to zero in ethumb.c file

[Michal J. <m.j...@sa...>]

Hi,

 

I found some bugs in ethumb and I have prepared a patch which fixed it.

 

In functions ethumb_calculate_aspect_from_ratio,
ethumb_calculate_fill_from_ratio, ethumb_plugin_image_resize and
ethumb_image_save Ethumb object is not checked if is NULL, what can cause
segmentation fault.

 

In functions ethumb_calculate_aspect and ethumb_calculate_fill divisor is
not checked if is equal to zero before division.

 

Please review the attached patch.

 

BR,

 

Michal Jagiello.
