Local crafted-file parsing requires the user to open the .psd (AV:L/UI:R), needs no prior privileges (PR:N), stays in the app's process (S:U), and yields full code execution (C/I/A:H).

6DescriptionNVD
A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the block_rem variable, occurs when a user opens a specially crafted .psd image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource blocks. This can ultimately result in arbitrary code execution, allowing the attacker to run malicious code on the victim's system.
AnalysisAI
Arbitrary code execution in GIMP's PSD import plugin allows an attacker to run code in the context of the user who opens a maliciously crafted .psd file. An unsigned integer underflow in the plugin's block_rem length variable (CWE-191) corrupts parsing of Photoshop layer resource blocks, letting attacker-controlled data be treated as trusted structures. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open an attacker-crafted .psd file in GIMP using the PSD import plugin, which is a standard bundled plugin, so no unusual configuration is needed on the target side. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict and should be reconciled before treating the 9.9 as face value. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker emails a graphic designer a .psd file disguised as a legitimate project asset, or seeds it on a file-sharing site. When the victim opens it in GIMP, the PSD plugin's block_rem counter underflows, the parser misreads attacker-controlled bytes as layer resource blocks, and code executes with the victim's privileges. … |
| Remediation | Upstream fix available (tracked in GNOME GIMP work item 16509); a specific released patched GIMP version is not stated in the available data, so apply your Linux distribution's GIMP security update as soon as it ships and monitor Red Hat's advisory (https://access.redhat.com/security/cve/CVE-2026-59090) and Bugzilla 2496584 for the exact fixed package NVR. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all systems running GIMP across design, engineering, and marketing departments; collect version information using gimp --version and cross-reference against GNOME's GIMP security advisories to identify affected systems. …
