The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6655-1 advisory.

  • An issue was discovered Binutils objdump before 2.39.3 allows attackers to cause a denial of service or other unspecified impacts via function bfd_mach_o_get_synthetic_symtab in match-o.c. (CVE-2022-47695)

  • GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the function load_separate_debug_files at dwarf2.c. The attacker could supply a crafted ELF file and cause a DNS attack. (CVE-2022-48063)

  • GNU Binutils before 2.40 was discovered to contain a memory leak vulnerability var the function find_abstract_instance in dwarf2.c. (CVE-2022-48065)

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