GIMP is prone to an overflow condition. This issue is triggered when an error occurs in plug-ins/common/psd.c during the decoding of a PSD image file header, which will result in a heap-based buffer overflow. With a specially crafted PSD file, a context-dependent attacker can potentially execute arbitrary code.
