#46433 [Fbk->Opn]: imagecreatefrom(...) leaks memory on errors

ID: 46433 User updated by: ak at pre-secure dot de Reported By: ak at pre-secure dot de -Status: Feedback +Status: Open Bug Type: GD related Operating System: Linux (OpenSUSE) PHP Version: 5.2.6 New Comment: I have to admit that my initial bugreport is a litte bit too unspecific. The memory problem only occures if the image is "tainted", f.e. taking a valid png and change a arbitrary line in the source. This will result in an error like this: PHP Warning: imagecreatefrompng(): gd-png: fatal libpng error: IDAT: CRC error in ---- and a rapid growth of the memory usage.
