dwarf parsing

About this tag
DWARF parsing refers to the process of reading and interpreting DWARF debugging information embedded in compiled binaries. On WindowsForum.com, discussions focus on memory safety vulnerabilities in the libdwarf library, including heap overflows, out-of-bounds reads, and division-by-zero errors that can crash tools like dwarfdump. These issues, tracked as CVEs such as CVE-2016-8681, CVE-2020-27545, and CVE-2019-14249, highlight risks in binary analysis and debugging utilities. Topics cover patching policies, defensive deployment, and how crafted ELF files exploit parsing flaws to cause denial-of-service conditions.

    CVE-2016-8681: libdwarf DWARF parsing heap overflow in dwarfdump

    The _dwarf_get_abbrev_for_code bug in libdwarf — tracked as CVE‑2016‑8681 — is a kernel‑level style memory‑safety defect in DWARF parsing that can be triggered by the widely used dwarfdump utility to crash processes that inspect debug sections in crafted binaries, and it remains a useful case...

    CVE-2020-27545: One byte OOB read in libdwarf line table fixed in 20201017

    libdwarf — the small, unassuming library that reads DWARF debug data — contains a parsing defect tracked as CVE‑2020‑27545 that, in releases prior to 20201017, can be induced by a crafted object to perform a one‑byte out‑of‑bounds read via an invalid pointer dereference in a malformed line...

    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...
