A double-free vulnerability was found in libdwarf. In a multiply-corrupted DWARF object, libdwarf may try to dealloc(free) an allocation twice, potentially causing unpredictable and various results.

The version of libdwarf installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-2002 advisory.

  - libdwarf: NULL pointer dereference due to corrupt line table header (CVE-2020-28163)

  - libdwarf before 20201017 has a one-byte out-of-bounds read because of an invalid pointer dereference via     an invalid line table in a crafted object. (CVE-2020-27545)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

    2024-10-24: CVE-2024-31745 was added to this advisory.

    In a multiply-corrupted DWARF object libdwarf may try to dealloc(free) an allocation twice.Results are     unpredictable and various. This has been a possibility since we added code to prevent leaks when     generating 'unattached' Dwarf_Error records (where there is no Dwarf_Debug available at the point of     error).The problem was introduced in libdwarf-0.1.0 in 2021. (CVE-2024-2002)

    Libdwarf v0.9.1 was discovered to contain a heap use-after-free via the dw_empty_errlist_item function at     /libdwarf/dwarf_alloc.c. (CVE-2024-31745)

Tenable has extracted the preceding description block directly from the tested product security advisory.
