Code execution via undersized directory-tracking array
Published Oct 3, 2024 · Updated Nov 3, 2025
Integer overflow in GNOME libgsf 1.14.52 allows attackers to execute arbitrary code through a crafted Compound Document Binary file. In ole_init_info, 32-bit arithmetic wraps while sizing the seen_before directory-tracking array, after which attacker-controlled directory links drive ole_dirent_new to read and write beyond that undersized allocation. Exploitation requires a consuming application or automated indexer to parse the file, and successful code execution runs with that process's privileges.
