"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-956 advisory.

    A vulnerability was found in GNU Binutils 2.43 and classified as critical. This issue affects the function
    _bfd_elf_gc_mark_rsec of the file elflink.c of the component ld. The manipulation leads to heap-based
    buffer overflow. The attack may be initiated remotely. The complexity of an attack is rather high. The
    exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The
    patch is named f9978defb6fab0bd8583942d97c112b0932ac814. It is recommended to apply a patch to fix this
    issue. (CVE-2025-1176)
