CVE-2025-14935

Code execution via unchecked dimension-name copy

Published Dec 23, 2025 · Updated Dec 23, 2025

Heap-based buffer overflow in Unidata NetCDF-C commit dbe0cbb9ff3f706009cf4ee011adf3e58d8a81c1 allows attackers to execute code via a crafted file. The dimension-name parser copies an attacker-controlled name into a fixed-length heap buffer without first validating its length. Exploitation requires context-dependent attackers to make the current user open the malicious file, and successful exploitation runs code with that user's privileges.
