An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.36. It is a stack-overflow issue in demangle_type in rust-demangle.c.(CVE-2021-32256)

A vulnerability has been found in GNU Binutils 2.45. The affected element is the function elf_swap_shdr in the library bfd/elfcode.h of the component Linker. The manipulation leads to heap-based buffer overflow. The attack must be carried out locally. The exploit has been disclosed to the public and may be used. The identifier of the patch is 9ca499644a21ceb3f946d1c179c38a83be084490. To fix this issue, it is recommended to deploy a patch. The code maintainer replied with [f]ixed for 2.46 .(CVE-2025-11083)

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):
