dwarf_elf_load_headers.c in libdwarf before 2019-07-05 allows attackers to cause a denial of service (division by zero) via an ELF file with a zero-size section group (SHT_GROUP), as demonstrated by dwarfdump.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libdwarf: division by zero in dwarf_elf_load_headers.c leading to DoS (CVE-2019-14249)

  - 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.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libdwarf: heap-based buffer over-read in dwarf_formsdata() (CVE-2017-9055)

  - Use-after-free vulnerability in dwarfdump in libdwarf 20130126 through 20140805 might allow remote     attackers to cause a denial of service (program crash) via a crafted ELF file. (CVE-2014-9482)

  - dwarf_leb.c in libdwarf allows attackers to cause a denial of service (SIGSEGV). (CVE-2015-8538)
