These non-security issues were fixed :

  - The AArch64 port now supports showing disassembly notes     which are emitted when inconsistencies are found with     the instruction that may result in the instruction being     invalid. These can be turned on with the option -M notes     to objdump.

  - The AArch64 port now emits warnings when a combination     of an instruction and a named register could be invalid.

  - Added O modifier to ar to display member offsets inside     an archive

  - The ADR and ADRL pseudo-instructions supported by the     ARM assembler now only set the bottom bit of the address     of thumb function symbols if the -mthumb-interwork     command line option is active.

  - Add --generate-missing-build-notes=[yes|no] option to     create (or not) GNU Build Attribute notes if none are     present in the input sources. Add a

    --enable-generate-build-notes=[yes|no] configure time     option to set the default behaviour. Set the default if     the configure option is not used to 'no'.

  - Remove -mold-gcc command-line option for x86 targets.

  - Add -O[2|s] command-line options to x86 assembler to     enable alternate shorter instruction encoding.

  - Add support for .nops directive. It is currently     supported only for x86 targets.

  - Speed up direct linking with DLLs for Cygwin and Mingw     targets.

  - Add a configure option --enable-separate-code to decide     whether

    -z separate-code should be enabled in ELF linker by     default. Default to yes for Linux/x86 targets. Note that
    -z separate-code can increase disk and memory size.

  - RISC-V: Fix symbol address problem with versioned     symbols 

  - Restore riscv64-elf cross prefix via symlinks

  - Fix pacemaker libqb problem with section start/stop     symbols

  - RISC-V: Don't enable relaxation in relocatable link

  - Prevent linking faiures on i386 with assertion     (bsc#1085784)

  - Fix symbol size bug when relaxation deletes bytes

  - Add --debug-dump=links option to readelf and
    --dwarf=links option to objdump which displays the     contents of any .gnu_debuglink or .gnu_debugaltlink     sections. Add a --debug-dump=follow-links option to     readelf and a --dwarf=follow-links option to objdump     which causes indirect links into separate debug info     files to be followed when dumping other DWARF sections.

  - Add support for loaction views in DWARF debug line     information.

  - Add -z separate-code to generate separate code PT_LOAD     segment.

  - Add '-z undefs' command line option as the inverse of     the '-z defs' option.

  - Add -z globalaudit command line option to force audit     libraries to be run for every dynamic object loaded by     an executable - provided that the loader supports this     functionality.

  - Tighten linker script grammar around file name     specifiers to prevent the use of SORT_BY_ALIGNMENT and     SORT_BY_INIT_PRIORITY on filenames. These would     previously be accepted but had no effect.

  - The EXCLUDE_FILE directive can now be placed within any     SORT_* directive within input section lists.

  - Fix linker relaxation with --wrap

  - An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU     Binutils 2.35.1. A heap-based buffer over-read can occur 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)

  - There is an open race window when writing output in the following utilities in GNU binutils version 2.35     and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as     part of a script updating binaries across different users), an unprivileged user can trick these utilities     into getting ownership of arbitrary files through a symlink. (CVE-2021-20197)

  - A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in
    _bfd_elf_slurp_secondary_reloc_section in elf.c due to the number of symbols not calculated correctly. The     highest threat from this vulnerability is to system availability. (CVE-2021-20284)

  - There's a flaw in the BFD library of binutils in versions before 2.36. An attacker who supplies a crafted     file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system     availability by way of excessive memory consumption. (CVE-2021-3487)

  - ** DISPUTED ** An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through     14.0. It permits the visual reordering of characters via control sequences, which can be used to craft     source code that renders different logic than the logical ordering of tokens ingested by compilers and     interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such     that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium     offers the following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.
    (CVE-2021-42574)

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