"The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.6:CLSA-2025:1765289483 advisory.

  - 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)

  - A vulnerability, which was classified as critical, was found in GNU elfutils 0.192. This affects the
    function process_symtab of the file readelf.c of the component eu-readelf. The manipulation of the
    argument D/a leads to buffer overflow. Local access is required to approach this attack. The exploit has
    been disclosed to the public and may be used. The identifier of the patch is
    5e5c0394d82c53e97750fe7b18023e6f84157b81. It is recommended to apply a patch to fix this issue.
    (CVE-2025-1365)

  - 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)
