About this tag
CVE-2019-14249 is a security vulnerability in the libdwarf library, specifically in the dwarf_elf_load_headers.c file, where a crafted ELF file can cause a division-by-zero error during DWARF parsing. This flaw, fixed upstream on July 5, 2019, can crash tools that rely on libdwarf, such as dwarfdump. The vulnerability affects software that processes DWARF debug data, which is commonly embedded in compiled binaries. Users of libdwarf or applications using it should update to the patched version to prevent denial-of-service attacks. This tag covers discussions about the vulnerability, its impact, and remediation steps.

  1. CVE-2019-14249: libdwarf division by zero in DWARF parsing

    The libdwarf library contained a small but consequential flaw in dwarf_elf_load_headers.c that, before the upstream fix on July 5, 2019, allowed a crafted ELF file to trigger a division‑by‑zero and crash consumers of DWARF debug data — a vulnerability tracked as CVE‑2019‑14249 and demonstrably...
