CVE-2026-118475 — Eog: eye of gnome: buffer overrun when parsing malicious png files with non-standard iccp chunk
A flaw was found in Eye of GNOME. When parsing a specially crafted PNG image containing malformed color profile metadata, the application fails to validate chunk boundaries while searching for a null terminator. An attacker could trick a user into opening a malicious image, causing the application to read past the allocated buffer. This issue can lead to an application crash, resulting in a Denial of Service (DoS), or potentially expose sensitive memory contents.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- No scoring signals.
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Red Hat Red Hat Enterprise Linux 7, Red Hat Red Hat Enterprise Linux 8, Red Hat Red Hat Enterprise Linux 9).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Exploitation requires user interaction: tighten email/web filtering and warn affected users.
- Search available logs for exploit probes matching the vulnerability class (memory corruption), errors and authentication anomalies.

Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Local/physical vector: focus on endpoint telemetry (EDR) from affected hosts.
- Correlate service crashes/restarts with inbound traffic; repeated crashes may indicate attempts.
