Technical details
An unsigned integer underflow exists in the `block_rem` variable within GIMP's PSD file format plugin. The vulnerability is triggered when parsing a specially crafted PSD file, causing parser confusion that enables an attacker to inject arbitrary data into layer resource blocks. This memory corruption flaw can be exploited to achieve arbitrary code execution. The attack requires user interaction (opening a malicious file) and no authentication. Patches should be available from GIMP/GNOME.
