CVE-2018-8881

Netwide Assembler (NASM) 2.13.02rc2 has a heap-based buffer over-read in the function tokenize in asm/preproc.c, related to an unterminated string.

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

It was discovered that NASM incorrectly handled certain source files. If a user or automated system were tricked into processing a specially crafted source file, a remote attacker could use these issues to cause NASM to crash, resulting in a denial of service, or possibly execute arbitrary code.
