Summary
A vulnerability in GIMP allows remote code execution via a heap-based buffer overflow when parsing HDR files. Exploitation requires user interaction, such as opening a malicious file or visiting a malicious page.
Risk Assessment
The organization risks full compromise of a user's workstation upon opening a crafted HDR file, potentially leading to data theft or lateral movement within the network.
Recommendation
Update GIMP to the latest patched version immediately. Until then, avoid opening HDR files from untrusted sources.
Original NVD description (English source)
GIMP HDR 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 HDR 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-28618.
