CVE-2024-0911Public exploit

Application crash via out-of-bounds heap read

Published Feb 6, 2024 · Updated Nov 4, 2025

Heap-based buffer overflow in GNU Indent 2.2.13 allows context-dependent attackers to crash the formatter via a crafted C source file. In set_buf_break in src/output.c, a comment followed by parentheses makes the formatter read a two-byte value four bytes before an allocated heap buffer. The user must run Indent on attacker-supplied source; the resulting memory fault aborts the local formatting process without a reported data impact.
