There's a flaw in binutils /bfd/pef.c. An attacker who is able to submit a crafted input file to be processed by the objdump program could cause a null pointer dereference. The greatest threat from this flaw is to application availability. This flaw affects binutils versions prior to 2.34.

An update of the crash package has been released.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - binutils: Integer overflow in cplus-dem.c:get_count() allows for denial of service (CVE-2018-18483)

  - The ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.30, does not validate the output_section pointer in the case of a symtab     entry with a SECTION type that has a 0 value, which allows remote attackers to cause a denial of     service (NULL pointer dereference and application crash) via a crafted file, as demonstrated by objcopy.
    (CVE-2018-10535)

  - An issue was discovered in arm_pt in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30.
    Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there are recursive     stack frames: demangle_arm_hp_template, demangle_class_name, demangle_fund_type, do_type, do_arg,     demangle_args, and demangle_nested_args. This can occur during execution of nm-new. (CVE-2018-12641)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

  Workaround :

    There is no known workaround at this time.

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

  - There's a flaw in binutils /bfd/pef.c. An attacker who is able to submit a crafted input file to be     processed by the objdump program could cause a null pointer dereference. The greatest threat from this     flaw is to application availability. This flaw affects binutils versions prior to 2.34. (CVE-2020-35495)

  - There's a flaw in bfd_pef_scan_start_address() of bfd/pef.c in binutils which could allow an attacker who     is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The     greatest threat of this flaw is to application availability. This flaw affects binutils versions prior to     2.34. (CVE-2020-35496)

  - There's a flaw in bfd_pef_parse_function_stubs of bfd/pef.c in binutils in versions prior to 2.34 which     could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL     pointer dereference. The greatest threat of this flaw is to application availability. (CVE-2020-35507)

  - There's a flaw in the BFD library of binutils in versions before 2.36. An attacker who supplies a crafted     file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system     availability by way of excessive memory consumption. (CVE-2021-3487)

  - An out of bounds flaw was found in GNU binutils objdump utility version 2.36. An attacker could use this     flaw and pass a large section to avr_elf32_load_records_from_section() probably resulting in a crash or in     some cases memory corruption. The highest threat from this vulnerability is to integrity as well as system     availability. (CVE-2021-3549)
