Summary: Security update for nasm

Details: 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 This update was imported from the SUSE:SLE-15:Update update project.
