DescriptionCVE.org

A flaw was found in the file-ico plugin in GIMP. When processing a specially crafted ICO image file, the plugin does not properly validate the used_clrs (palette count) parameter. This incorrect validation leads to improper memory bounds checking, resulting in a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents.

AnalysisAI

Heap out-of-bounds read in GIMP's file-ico plugin allows a local attacker to crash GIMP or leak limited heap memory contents by delivering a specially crafted ICO image file to a victim user. Affected packages span Red Hat Enterprise Linux 6 through 9. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the victim actively opens a specially crafted ICO image file in GIMP (UI:R - mandatory user interaction, no zero-click path exists). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 6.1 Medium score is well-calibrated: AV:L and UI:R together mean this is not remotely exploitable without a separate delivery step, and the primary impact is a crash (A:H) with only limited heap disclosure (C:L) and no integrity impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Apply the GIMP package update for the relevant RHEL version as released through Red Hat's security channels; consult https://access.redhat.com/security/cve/CVE-2026-82328 for the specific patched package version - no exact fix version is confirmed in the current available data. … Detailed patch versions, workarounds, and compensating controls in full report.
