The version of binutils installed on the remote host is prior to 2.29.1-31. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2401 advisory.
A memory consumption issue in get_data function in binutils/nm.c in GNU nm before 2.34 allows attackers to cause a denial of service via crafted command. (CVE-2020-19724)
Heap-based Buffer Overflow in function bfd_getl32 in Binutils objdump 3.37. (CVE-2021-46174)
An issue was discovered in Binutils readelf 2.38.50, reachable assertion failure in function display_debug_names allows attackers to cause a denial of service. (CVE-2022-35205)
An issue was discovered function stab_demangle_v3_arg in stabs.c in Binutils 2.34 thru 2.38, allows attackers to cause a denial of service due to memory leaks. (CVE-2022-47007)
An issue was discovered function make_tempdir, and make_tempname in bucomm.c in Binutils 2.34 thru 2.38, allows attackers to cause a denial of service due to memory leaks. (CVE-2022-47008)
An issue was discovered function pr_function_type in prdbg.c in Binutils 2.34 thru 2.38, allows attackers to cause a denial of service due to memory leaks. (CVE-2022-47010)
GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the function bfd_dwarf2_find_nearest_line_with_alt at dwarf2.c. The attacker could supply a crafted ELF file and cause a DNS attack. (CVE-2022-48064)
A potential heap based buffer overflow was found in _bfd_elf_slurp_version_tables() in bfd/elf.c. This may lead to loss of availability. (CVE-2023-1972)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
