The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6544-1 advisory.

  • An issue was discovered in binutils libbfd.c 2.36 relating to the auxiliary symbol data allows attackers to read or write to system memory or cause a denial of service. (CVE-2020-19726)

  • 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)

  • In GNU Binutils before 2.40, there is a heap-buffer-overflow in the error function bfd_getl32 when called from the strip_main function in strip-new via a crafted file. (CVE-2022-38533)

  • An illegal memory access flaw was found in the binutils package. Parsing an ELF file containing corrupt symbol version information may result in a denial of service. This issue is the result of an incomplete fix for CVE-2020-16599. (CVE-2022-4285)

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