In short

GIMP has a bug when opening PSD image files that allows attackers to run harmful code on your computer if you open a malicious PSD file. The problem is that the program doesn't properly check file data before processing it, leading to a memory error.

Technical detail

An integer overflow in GIMP's PSD file parser occurs due to insufficient validation of user-supplied data during buffer allocation. Remote attackers can craft malicious PSD files that trigger this overflow, enabling arbitrary code execution in the GIMP process context. User interaction (opening the file) is required to exploit this vulnerability.

Summary generated and translated by AI from the official description.
GIMP PSD File Parsing Integer 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 PSD files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28807.
