Vulnerability Data
A maliciously-crafted image can cause excessive CPU consumption in decoding. A tiled image with a height of 0 and a very large width can cause excessive CPU consumption, despite the image size (width * height) appearing to be zero.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Secure development lifecycle requires input validation and loop bounds, directly limiting excessive iteration.
Application security requirements include resource-consumption limits that prevent unbounded loops.
Secure architecture principles mandate defensive coding patterns such as loop termination checks.
Secure coding standards explicitly forbid unbounded loops and require explicit iteration limits.
Security testing can detect excessive iteration through stress and fuzz testing.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-834, a class-level weakness, and none of its children carries one either.
