What the CVE records say

CVE-2020-35493 — A flaw exists in binutils in bfd/pef.c. An attacker who is able to submit a crafted PEF file to be parsed by objdump could cause a heap buffer overflow -> out-of-bounds read that could lead to an impact to application availability. This flaw affects binutils versions prior to 2.34.

CVE-2020-35494 — There's a flaw in binutils /opcodes/tic4x-dis.c. An attacker who is able to submit a crafted input file to be processed by binutils could cause usage of uninitialized memory. The highest threat is to application availability with a lower threat to data confidentiality. This flaw affects binutils versions prior to 2.34.

CVE-2020-35495 — There's a flaw in binutils /bfd/pef.c. An attacker who is able to submit a crafted input file to be processed by the objdump program could cause a null pointer dereference. The greatest threat from this flaw is to application availability. This flaw affects binutils versions prior to 2.34.

CVE-2020-35496 — There's a flaw in bfd_pef_scan_start_address() of bfd/pef.c in binutils which could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The greatest threat of this flaw is to application availability. This flaw affects binutils versions prior to 2.34.

CVE-2020-35507 — There's a flaw in bfd_pef_parse_function_stubs of bfd/pef.c in binutils in versions prior to 2.34 which could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The greatest threat of this flaw is to application availability.

What to do

Check the affected products listed above against the official advisory's affected-versions table — that is where the exact ONTAP 9 release, ONTAP tool, or management product versions are named.
If affected and a fixed release exists, plan the upgrade — see the ONTAP upgrade runbook.
If exploitation is listed as "active", treat remediation as urgent and review exposure (management LIFs, ONTAP S3, SnapMirror endpoints).
