Summary
A flaw was found in the golang.org/x/image/tiff component. This vulnerability allows a remote attacker to cause a denial of service (DoS) by providing a specially crafted, invalid TIFF image. When the TIFF decoder attempts to process an image with an out-of-bounds strip offset, it can panic, leading to the unavailability of the affected system.
Remediation
There is no complete inline mitigation for this issue; the fix requires upgrading golang.org/x/image to version 0.43.0 or later, which validates the strip offset before use. Where an immediate upgrade is not possible, exposure can be reduced by not decoding untrusted or externally supplied TIFF images, or by isolating TIFF decoding in a sandboxed, restartable worker process so a panic does not crash the primary service.

01
What, why and how
The TIFF decoder can panic when decoding an invalid image with an out-of-bounds strip offset.
What
The TIFF decoder can panic when decoding an invalid image with an out-of-bounds strip offset.
Why
The product reads data past the end, or before the beginning, of the intended buffer.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No confirmed evidence
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.None recorded
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
Likely attack path
