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

    A vulnerability was found in GNU elfutils 0.192. It has been declared as critical. Affected by this
    vulnerability is the function dump_data_section/print_string_section of the file readelf.c of the
    component eu-readelf. The manipulation of the argument z/x leads to buffer overflow. An attack has to be
    approached locally. The exploit has been disclosed to the public and may be used. The identifier of the
    patch is 73db9d2021cab9e23fd734b0a76a612d52a6f1db. It is recommended to apply a patch to fix this
    issue.(CVE-2025-1372)

    A vulnerability classified as problematic was found in GNU elfutils 0.192. This vulnerability affects the
    function elf_strptr in the library /libelf/elf_strptr.c of the component eu-strip. The manipulation leads
    to denial of service. It is possible to launch the attack on the local host. The complexity of an attack
    is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and
    may be used. The name of the patch is b16f441cca0a4841050e3215a9f120a6d8aea918. It is recommended to apply
    a patch to fix this issue.(CVE-2025-1376)

    A vulnerability, which was classified as problematic, has been found in GNU elfutils 0.192. This issue
    affects the function gelf_getsymshndx of the file strip.c of the component eu-strip. The manipulation
    leads to denial of service. The attack needs to be approached locally. The exploit has been disclosed to
    the public and may be used. The identifier of the patch is fbf1df9ca286de3323ae541973b08449f8d03aba. It is
    recommended to apply a patch to fix this issue.(CVE-2025-1377)

    A vulnerability has been found in GNU elfutils 0.192 and classified as critical. This vulnerability
    affects the function __libdw_thread_tail in the library libdw_alloc.c of the component eu-readelf. The
    manipulation of the argument w leads to memory corruption. The attack can be initiated remotely. The
    complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been
    disclosed to the public and may be used. The name of the patch is
    2636426a091bd6c6f7f02e49ab20d4cdc6bfc753. It is recommended to apply a patch to fix this
    issue.(CVE-2025-1352)
