A flaw was found in binutils readelf 2.35 program. An attacker who is able to convince a victim using readelf to read a crafted file could trigger a stack buffer overflow, out-of-bounds write of arbitrary data supplied by the attacker. The highest impact of this flaw is to confidentiality, integrity, and availability.

An update of the binutils package has been released.

An update of the crash package has been released.

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

The remote host is affected by the vulnerability described in GLSA-202208-30 (GNU Binutils: Multiple Vulnerabilities)

  - There is an open race window when writing output in the following utilities in GNU binutils version 2.35     and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as     part of a script updating binaries across different users), an unprivileged user can trick these utilities     into getting ownership of arbitrary files through a symlink. (CVE-2021-20197)

  - A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in
    _bfd_elf_slurp_secondary_reloc_section in elf.c due to the number of symbols not calculated correctly. The     highest threat from this vulnerability is to system availability. (CVE-2021-20284)

  - A flaw was found in binutils readelf 2.35 program. An attacker who is able to convince a victim using     readelf to read a crafted file could trigger a stack buffer overflow, out-of-bounds write of arbitrary     data supplied by the attacker. The highest impact of this flaw is to confidentiality, integrity, and     availability. (CVE-2021-20294)

  - 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)

  - A flaw was discovered in GNU libiberty within demangle_path() in rust-demangle.c, as distributed in GNU     Binutils version 2.36. A crafted symbol can cause stack memory to be exhausted leading to a crash.
    (CVE-2021-3530)

  - 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)

  - stab_xcoff_builtin_type in stabs.c in GNU Binutils through 2.37 allows attackers to cause a denial of     service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-     of-bounds write. NOTE: this issue exists because of an incorrect fix for CVE-2018-12699. (CVE-2021-45078)

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0934-1 advisory.

  - A double free vulnerability exists in the Binary File Descriptor (BFD) (aka libbrd) in GNU Binutils 2.35     in the process_symbol_table, as demonstrated in readelf, via a crafted file. (CVE-2020-16590)

  - A Denial of Service vulnerability exists in the Binary File Descriptor (BFD) in GNU Binutils 2.35 due to     an invalid read in process_symbol_table, as demonstrated in readeif. (CVE-2020-16591)

  - A use after free issue exists in the Binary File Descriptor (BFD) library (aka libbfd) in GNU Binutils     2.34 in bfd_hash_lookup, as demonstrated in nm-new, that can cause a denial of service via a crafted file.
    (CVE-2020-16592)

  - A Null Pointer Dereference vulnerability exists in the Binary File Descriptor (BFD) library (aka libbfd),     as distributed in GNU Binutils 2.35, in scan_unit_for_symbols, as demonstrated in addr2line, that can     cause a denial of service via a crafted file. (CVE-2020-16593)

  - A Null Pointer Dereference vulnerability exists in the Binary File Descriptor (BFD) library (aka libbfd),     as distributed in GNU Binutils 2.35, in _bfd_elf_get_symbol_version_string, as demonstrated in nm-new,     that can cause a denial of service via a crafted file. (CVE-2020-16599)

  - An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU     Binutils 2.35.1. A heap-based buffer over-read can occur in bfd_getl_signed_32 in libbfd.c because     sh_entsize is not validated in _bfd_elf_slurp_secondary_reloc_section in elf.c. (CVE-2020-35448)

  - A flaw exists in binutils in bfd/pef.c. An attacker who is able to submit a crafted PEF file to be parsed     by objdump could cause a heap buffer overflow -> out-of-bounds read that could lead to an impact to     application availability. This flaw affects binutils versions prior to 2.34. (CVE-2020-35493)

  - 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)
