medium Nessus Plugin ID 357833

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-2021_4364 advisory.

 * binutils: Excessive debug section size can cause excessive memory consumption in bfd's dwarf2.c read_section() (CVE-2021-3487)

 * binutils: Race window allows users to own arbitrary files (CVE-2021-20197)

 * binutils: Heap-based buffer overflow in bfd_getl_signed_32() in libbfd.c because sh_entsize is not validated in _bfd_elf_slurp_secondary_reloc_section() in elf.c (CVE-2020-35448)

 * binutils: Heap-based buffer overflow in _bfd_elf_slurp_secondary_reloc_section in elf.c (CVE-2021-20284)

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in CIQ advisory crlsa-2021_4364.
