CVE-2024-25443Public exploit

Heap memory corruption via use-after-free

Published Feb 9, 2024 · Updated Nov 4, 2025

Use-after-free in Hugin 2022.0.0 allows attackers to corrupt heap memory when a user processes a crafted input image. The HuginBase::ImageVariable::linkWith function accesses an image-variable allocation after it has been freed during input parsing. Exploitation requires user interaction with attacker-supplied input and can crash the process or compromise data handled with that user's privileges.
