An update that solves 13 vulnerabilities and has one errata
is now available.

Description:

This update for nasm fixes the following issues:

nasm was updated to version 2.14.02.

This allows building of Mozilla Firefox 78ESR and also contains lots of
bugfixes, security fixes and improvements.

  • Fix crash due to multiple errors or warnings during the code generation
    pass if a list file is specified.
  • Create all system-defined macros defore processing command-line given
    preprocessing directives (-p, -d, -u, --pragma, --before).
  • If debugging is enabled, define a DEBUG_FORMAT predefined macro. See
    section 4.11.7.
  • Fix an assert for the case in the obj format when a SEG operator refers
    to an EXTERN symbol declared further down in the code.
  • Fix a corner case in the floating-point code where a binary, octal or
    hexadecimal floating-point having at least 32, 11, or 8 mantissa digits
    could produce slightly incorrect results under very specific conditions.
  • Support -MD without a filename, for gcc compatibility. -MF can be used
    to set the dependencies output filename. See section 2.1.7.
  • Fix -E in combination with -MD. See section 2.1.21.
  • Fix missing errors on redefined labels; would cause convergence failure
    instead which is very slow and not easy to debug.
  • Duplicate definitions of the same label with the same value is now
    explicitly permitted (2.14 would allow it in some circumstances.)
  • Add the option --no-line to ignore %line directives in the source. See
    section 2.1.33 and section 4.10.1.
  • Changed -I option semantics by adding a trailing path separator
    unconditionally.
  • Fixed null dereference in corrupted invalid single line macros.
  • Fixed division by zero which may happen if source code is malformed.
  • Fixed out of bound access in processing of malformed segment override.
  • Fixed out of bound access in certain EQU parsing.
  • Fixed buffer underflow in float parsing.
  • Added SGX (Intel Software Guard Extensions) instructions.
  • Added +n syntax for multiple contiguous registers.
  • Fixed subsections_via_symbols for macho object format.
  • Added the --gprefix, --gpostfix, --lprefix, and --lpostfix command line
    options, to allow command line base symbol renaming. See section 2.1.28.
  • Allow label renaming to be specified by %pragma in addition to from the
    command line. See section 6.9.
  • Supported generic %pragma namespaces, output and debug. See section 6.10.
  • Added the --pragma command line option to inject a %pragma directive.
    See section 2.1.29.
  • Added the --before command line option to accept preprocess statement
    before input. See section 2.1.30.
  • Added AVX512 VBMI2 (Additional Bit Manipulation), VNNI (Vector Neural
    Network), BITALG (Bit Algorithm), and GFNI (Galois Field New
    Instruction) instructions.
  • Added the STATIC directive for local symbols that should be renamed
    using global-symbol rules. See section 6.8.
  • Allow a symbol to be defined as EXTERN and then later overridden as
    GLOBAL or COMMON. Furthermore, a symbol declared EXTERN and then defined
    will be treated as GLOBAL. See section 6.5.
  • The GLOBAL directive no longer is required to precede the definition of
    the symbol.
  • Support private_extern as macho specific extension to the GLOBAL
    directive. See section 7.8.5.
  • Updated UD0 encoding to match with the specification
  • Added the --limit-X command line option to set execution limits. See
    section 2.1.31.
  • Updated the Codeview version number to be aligned with MASM.
  • Added the --keep-all command line option to preserve output files. See
    section 2.1.32.
  • Added the --include command line option, an alias to -P (section 2.1.18).
  • Added the --help command line option as an alias to -h (section 3.1).
  • Added -W, -D, and -Q suffix aliases for RET instructions so the operand
    sizes of these instructions can be encoded without using o16, o32 or o64.

New upstream version 2.13.03:

  • Add flags: AES, VAES, VPCLMULQDQ
  • Add VPCLMULQDQ instruction
  • elf: Add missing dwarf loc section
  • documentation updates
