CVE-2026-18309

The GIMP is an image composition and editing program, which can be used for creating logos and other graphics for Web pages. The GIMP offers many tools and filters, and provides a large image manipulation toolbox, including channel operations and layers, effects, subpixel imaging and antialiasing, and conversions, together with multilevel undo. The GIMP offers a scripting facility, but many of the included scripts rely on fonts that we cannot distribute.

Security Fix(es):

A vulnerability was found in GIMP (Image Processing Software) (affected version unknown). It has been classified as critical. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability.(CVE-2026-18301)

A vulnerability was found in GIMP (GNU Image Manipulation Program) TIF file parser. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This vulnerability impacts confidentiality, integrity, and availability.(CVE-2026-18302)

A buffer overflow vulnerability has been found in the TIF file parser of GIMP (GNU Image Manipulation Program). The vulnerability is classified as critical. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This vulnerability could affect confidentiality, integrity, and availability of the system.(CVE-2026-18303)

A vulnerability, which was classified as critical, was found in GIMP (Image Processing Software). CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability.(CVE-2026-18304)

A vulnerability, which was classified as critical, has been found in GIMP (Image Processing Software) in the TIF file parser. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability.(CVE-2026-18305)

An integer overflow vulnerability was found in the SGI file parser of GIMP (GNU Image Manipulation Program). The vulnerability is classified as critical with CWE-190 (Integer Overflow or Wraparound). The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact, it is known to affect confidentiality, integrity, and availability.(CVE-2026-18306)

A vulnerability was found in GIMP (GNU Image Manipulation Program). It has been rated as critical. The TIF file parser performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. The vulnerability impacts confidentiality, integrity, and availability.(CVE-2026-18308)

A vulnerability classified as critical has…

GIMP APNG 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 APNG 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-29401.

This update to v. 3.2.8 fixes several security issues.

These are all security issues fixed in the gimp-3.2.6-1.1 package on the GA media of openSUSE Tumbleweed.
