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.
AnalysisAI
Heap-based buffer overflow in GIMP's PSP (Paint Shop Pro) file parser enables remote code execution when processing malicious PSP image files. Unauthenticated attackers can execute arbitrary code with user privileges by convincing targets to open crafted PSP files. …

RemediationAI
Within 24 hours: Inventory all systems running GIMP and disable or restrict PSP file handling via file association removal and browser download blocking. Within 7 days: Issue security awareness communication warning users against opening PSP files from untrusted sources, and implement application whitelisting to restrict GIMP execution if not business-critical. …
