HighCVSS 7.8Exploitation Probability (EPSS)
Low risk40th percentile - higher than 40% of all known CVEs
Summary
A vulnerability in GIMP's WBMP file parsing allows an integer overflow before buffer allocation. Exploitation requires user interaction (opening a malicious file or page). It can lead to remote code execution in the context of the process.
Risk Assessment
A user opening a malicious WBMP file could allow arbitrary code execution on the workstation. This poses a significant risk if employees process untrusted image files.
Recommendation
Update GIMP to a patched version or avoid opening untrusted WBMP files. Consider restricting processing of such files to isolated environments.

- CVE-2017-17785High
In GIMP 2.8.22, there is a heap-based buffer overflow in the fli_read_brun function in plug-ins/file-fli/fli.c.
- CVE-2017-17784High
In GIMP 2.8.22, there is a heap-based buffer over-read in load_image in plug-ins/common/file-gbr.c, related to mishandling of UTF-8 data.
- CVE-2016-4994High
A use-after-free vulnerability in the xcf_load_image function in xcf-load.c in GIMP allows remote attackers to cause a denial of service (program crash) or possibly execute arbitrary code via a crafted XCF file.
- CVE-2026-119528High
A flaw was found in GIMP's PSD plug-in: the image resource header loader uses an incorrect destination size when copying a converted resource name into a fixed stack buffer. Opening a crafted PSD file can cause a stack-based buffer overflow, leading to a crash and potentially arbitrary code execution.
- CVE-2026-92183High
GIMP contains a stack-based buffer overflow in APNG file parsing due to lack of proper validation of user-supplied data length before copying it to a stack buffer. A remote attacker can achieve arbitrary code execution in the context of the current process if the target opens a malicious file or visits a malicious page.
- CVE-2026-112261High
A flaw was found in GIMP. Opening a crafted XCF that selects a path and then fails to load that path can cause a use-after-free in the main process, leading to a crash and potentially arbitrary code execution.
- CVE-2026-112258High
A flaw was found in GIMP. The XCF loader can leave a dangling pointer in the linked-channels list when a linked channel is later destroyed via a selection property. Opening a crafted XCF file can cause a use-after-free in the main GIMP process, leading to a crash and potentially arbitrary code execution.
Original NVD description (English source)
GIMP WBMP 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 WBMP 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-27878.
