CVE-2024-29645

Code execution via zero-count DWARF abbreviation

Published Dec 2, 2024 · Updated Mar 13, 2025

Heap buffer overflow in radare2 5.8.8 allows local users to execute arbitrary code by opening a crafted ELF file with DWARF data. In libr/bin/dwarf.c, parse_die increments the DIE attribute count after a zero-count abbreviation causes calloc(0), then later clears beyond the zero-sized allocation. Exploitation requires analysis of a crafted AMD64 ELF file with DWARF debug information, and successful corruption runs code in the radare2 process.
