LowCVSS 3.3Exploitation Probability (EPSS)
Low risk44th percentile - higher than 44% of all known CVEs
Summary
A flaw was found in GIMP's PSP (Paint Shop Pro) file parser. A remote attacker could exploit an integer overflow in the read_creator_block() function by providing a specially crafted PSP image file, where a 32-bit length value is used for memory allocation without proper validation, leading to a heap overflow and an out-of-bounds write.
Risk Assessment
Successful exploitation could result in an application-level denial of service, such as GIMP crashing or hanging when opening a malicious file. The risk affects users who open untrusted image files.
Recommendation
Update GIMP to a version containing the fix. Until patched, avoid opening PSP files from untrusted sources.

In GIMP 2.8.22, there is a heap-based buffer over-read in the read_creator_block handler in plug-ins/common/file-psp.c.
- CVE-2017-17786High
In GIMP 2.8.22, there is a heap-based buffer over-read in ReadImage in plug-ins/common/file-tga.c, related to an unexpected bits-per-pixel value for an RGBA image.
- 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)
A flaw was found in GIMP's PSP (Paint Shop Pro) file parser. A remote attacker could exploit an integer overflow vulnerability in the read_creator_block() function by providing a specially crafted PSP image file. This vulnerability occurs when a 32-bit length value from the file is used for memory allocation without proper validation, leading to a heap overflow and an out-of-bounds write. Successful exploitation could result in an application level denial of service.
