Descriptions

The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68.

El codificador de imágenes PALM en el archivo coders/palm.c realiza una llamada inapropiada a la función AcquireQuantumMemory() en la rutina WritePALMImage() porque necesita estar desplazada por 256. Esto puede causar una lectura fuera de límites más adelante en la rutina. El parche agrega 256 a bytes_per_row en la llamada a AcquireQuantumMemory(). Esto podría afectar la confiabilidad. Este fallo afecta a ImageMagick versiones anteriores a 7.0.8-68
