These are all security issues fixed in the binutils-2.41-1.2 package on the GA media of openSUSE Tumbleweed.

This update for binutils fixes the following issues:

Update to version 2.41 [jsc#PED-5778]:

• The MIPS port now supports the Sony Interactive Entertainment Allegrex processor, used with the PlayStation Portable, which implements the MIPS II ISA along with a single-precision FPU and a few implementation-specific integer instructions.

• Objdump's --private option can now be used on PE format files to display the fields in the file header and section headers.

• New versioned release of libsframe: libsframe.so.1. This release introduces versioned symbols with version node name LIBSFRAME_1.0. This release also updates the ABI in an incompatible way: this includes removal of sframe_get_funcdesc_with_addr API, change in the behavior of sframe_fre_get_ra_offset and sframe_fre_get_fp_offset APIs.

• SFrame Version 2 is now the default (and only) format version supported by gas, ld, readelf and objdump.

• Add command-line option, --strip-section-headers, to objcopy and strip to remove ELF section header from ELF file.

• The RISC-V port now supports the following new standard extensions:

  • Zicond (conditional zero instructions)
  • Zfa (additional floating-point instructions)
  • Zvbb, Zvbc, Zvkg, Zvkned, Zvknh[ab], Zvksed, Zvksh, Zvkn, Zvknc, Zvkng, Zvks, Zvksc, Zvkg, Zvkt (vector crypto instructions)

• The RISC-V port now supports the following vendor-defined extensions:

  • XVentanaCondOps

• Add support for Intel FRED, LKGS and AMX-COMPLEX instructions.

• A new .insn directive is recognized by x86 gas.

• Add SME2 support to the AArch64 port.

• The linker now accepts a command line option of --remap-inputs <PATTERN>=<FILE> to relace any input file that matches <PATTERN> with <FILE>. In addition the option --remap-inputs-file=<FILE> can be used to specify a file containing any number of these remapping directives.

• The linker command line option --print-map-locals can be used to include local symbols in a linker map. (ELF targets only).

• For most ELF based targets, if the --enable-linker-version option is used then the version of the linker will be inserted as a string into the .comment section.

• The linker script syntax has a new command for output sections: ASCIZ 'string' This will insert a zero-terminated string at the current location.

• Add command-line option, -z nosectionheader, to omit ELF section header.

• Contains fixes for these non-CVEs (not security bugs per upstreams SECURITY.md):
