"The remote NewStart CGSL host, running version MAIN 7.02, has binutils packages installed that are affected by multiple
vulnerabilities:

  - A vulnerability classified as critical has been found in GNU Binutils up to 2.44. This affects the
    function debug_type_samep of the file /binutils/debug.c of the component objdump. The manipulation leads
    to memory corruption. Local access is required to approach this attack. The exploit has been disclosed to
    the public and may be used. It is recommended to apply a patch to fix this issue. (CVE-2025-5245)

  - A flaw has been found in GNU Binutils 2.45. Impacted is the function _bfd_elf_parse_eh_frame of the file
    bfd/elf-eh-frame.c of the component Linker. Executing manipulation can lead to heap-based buffer overflow.
    The attack is restricted to local execution. The exploit has been published and may be used. This patch is
    called ea1a0737c7692737a644af0486b71e4a392cbca8. A patch should be applied to remediate this issue. The
    code maintainer replied with [f]ixed for 2.46. (CVE-2025-11082)

  - 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)

  - A vulnerability was found in GNU Binutils up to 2.44. It has been rated as critical. Affected by this
    issue is the function elf_gc_sweep of the file bfd/elflink.c of the component ld. The manipulation leads
    to memory corruption. An attack has to be approached locally. The exploit has been disclosed to the public
    and may be used. Upgrading to version 2.45 is able to address this issue. It is recommended to upgrade the
    affected component. (CVE-2025-5244)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
