Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3593-1 advisory.

- An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character.
(CVE-2019-12972)

- An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. simple_object_elf_match in simple-object-elf.c does not check for a zero shstrndx value, leading to an integer overflow and resultant heap-based buffer overflow. (CVE-2019-14250)

- apply_relocations in readelf.c in GNU Binutils 2.32 contains an integer overflow that allows attackers to trigger a write access violation (in byte_put_little_endian function in elfcomm.c) via an ELF file, as demonstrated by readelf. (CVE-2019-14444)

- find_abstract_instance in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32, allows remote attackers to cause a denial of service (infinite recursion and application crash) via a crafted ELF file. (CVE-2019-17450)

- An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an integer overflow leading to a SEGV in _bfd_dwarf2_find_nearest_line in dwarf2.c, as demonstrated by nm. (CVE-2019-17451)

- An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an out-of-bounds read leading to a SEGV in bfd_getl32 in libbfd.c, when called from pex64_get_runtime_function in pei-x86_64.c. (CVE-2019-9074)

- An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is a heap-based buffer overflow in _bfd_archive_64_bit_slurp_armap in archive64.c.
(CVE-2019-9075)

- An issue was discovered in GNU Binutils 2.32. It is a heap-based buffer overflow in process_mips_specific in readelf.c via a malformed MIPS option section. (CVE-2019-9077)

- 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)

- 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)

- 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)

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