"According to the versions of the binutils package installed, the EulerOS Virtualization installation on the remote host
is affected by the following vulnerabilities :

    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 was found in GNU Binutils 2.44 and classified as problematic. This issue affects the
    function process_debug_info of the file binutils/dwarf.c of the component DWARF Section Handler. The
    manipulation leads to memory leak. Attacking locally is a requirement. The identifier of the patch is
    e51fdff7d2e538c0e5accdd65649ac68e6e0ddd4. It is recommended to apply a patch to fix this
    issue.(CVE-2025-8225)

    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)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization binutils security
advisory.
