## Description

GIMP PSP File Parsing Heap-based Buffer Overflow Remote Code Execution
Vulnerability. This vulnerability allows remote attackers to execute
arbitrary code on affected installations of GIMP. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page or open a malicious file.
The specific flaw exists within the parsing of PSP files. The issue results
from the lack of proper validation of the length of user-supplied data
prior to copying it to a heap-based buffer. An attacker can leverage this
vulnerability to execute code in the context of the current process. Was
ZDI-CAN-28874.
