Bug #73315 [NEW]: Potential memory leak in image2wbmp()

From: cmb Operating system: * PHP version: 7.0.11 Package: GD related Bug Type: Bug Bug description:Potential memory leak in image2wbmp() Description: ------------ If gdImageColorAllocate() or gdImageTrueColorToPalette() fails in _php_image_bw_convert()[1] the function returns without destroying im_dest, and as such causing a memory leak. It is not possible to provide a reproduce script, because gdImageColorAllocate() is not supposed to ever fail in this context, and gdImageTrueColorToPalette() would only fail due to out-of-memory conditions which most likely already have been causing a fatal PHP error due to memory_limit.
