Summary

gegl04 security update

Details

GEGL (Generic Graphics Library) is a data flow based image processing framework, providing floating point processing and non-destructive image processing capabilities to GNU Image Manipulation Program and other projects (imgflo, GNOME Photos, gcut, iconographer, …) With GEGL you chain together processing operations to represent the desired image processing pipeline. GEGL provides operations for image loading and storing, color adjustments, GIMPs artistic filters and more forms of image processing GEGL can also be used from the commandline. The primary repository for the GEGL source code in GNOME git, and at GIMPs download site tarball releases. GEGL is Free Software, and both new functionality in new operations as well as relevant development, enhancement requests, patches and bug reports for GEGL at gitlab.gnome.org/GNOME/gegl , Finanical support for fun new filters and capabilities as well as gardening/janitor bits and offshoot new color related infrastructure as part of project maintainership is welcome through the patreon campaign at GIMPs donation page.

Security Fix(es):

The specific flaw exists within the parsing of HDR 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-29289.(CVE-2026-18300)

Severity

Title

GIMP HDR File Parsing Integer Overflow Remote Code Execution Vulnerability

Summary

GIMP HDR 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 HDR 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-29289.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
