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

  - ** DISPUTED ** An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through     14.0. It permits the visual reordering of characters via control sequences, which can be used to craft     source code that renders different logic than the logical ordering of tokens ingested by compilers and     interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such     that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium     offers the following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.
    (CVE-2021-42574)

  - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version MAIN 6.02, has binutils packages installed that are affected by multiple vulnerabilities:

  - process_cu_tu_index in dwarf.c in GNU Binutils 2.30 allows remote attackers to cause a denial of service     (heap-based buffer over-read and application crash) via a crafted binary file, as demonstrated by readelf.
    (CVE-2018-10372)

  - The elf_object_p function in elfcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.29.1, has an unsigned integer overflow because bfd_size_type multiplication     is not used. A crafted ELF file allows remote attackers to cause a denial of service (application crash)     or possibly have unspecified other impact. (CVE-2018-6323)

  - The bfd_get_debug_link_info_1 function in opncls.c in the Binary File Descriptor (BFD) library (aka     libbfd), as distributed in GNU Binutils 2.30, has an unchecked strnlen operation. Remote attackers could     leverage this vulnerability to cause a denial of service (segmentation fault) via a crafted ELF file.
    (CVE-2018-6759)

  - In the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd),     as distributed in GNU Binutils 2.30, an index is not validated, which allows remote attackers to cause a     denial of service (segmentation fault) or possibly have unspecified other impact via a crafted file, as     demonstrated by objcopy of a COFF object. (CVE-2018-7208)

  - The parse_die function in dwarf1.c in the Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (integer overflow     and application crash) via an ELF file with corrupt dwarf1 debug information, as demonstrated by nm.
    (CVE-2018-7568)

  - dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30,     allows remote attackers to cause a denial of service (integer underflow or overflow, and application     crash) via an ELF file with a corrupt DWARF FORM block, as demonstrated by nm. (CVE-2018-7569)

  - The assign_file_positions_for_non_load_sections function in elf.c in the Binary File Descriptor (BFD)     library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of     service (NULL pointer dereference and application crash) via an ELF file with a RELRO segment that lacks a     matching LOAD segment, as demonstrated by objcopy. (CVE-2018-7570)

  - The swap_std_reloc_in function in aoutx.h in the Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service     (aout_32_swap_std_reloc_out NULL pointer dereference and application crash) via a crafted ELF file, as     demonstrated by objcopy. (CVE-2018-7642)

  - The display_debug_ranges function in dwarf.c in GNU Binutils 2.30 allows remote attackers to cause a     denial of service (integer overflow and application crash) or possibly have unspecified other impact via a     crafted ELF file, as demonstrated by objdump. (CVE-2018-7643)

  - The bfd_section_from_shdr function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (segmentation     fault) via a large attribute section. (CVE-2018-8945)

  - 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)

  - 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)

The version of AOS installed on the remote host is prior to 5.20.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.3 advisory.

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document. (CVE-2016-4658)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.

  - Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.

Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.
    (CVE-2021-42574)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing     filenames with two or more newlines where selected content and the target file names are embedded in     crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write     arbitrary files on the system. (CVE-2022-1271)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

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