EulerOS Virtualization 3.0.2.2 : binutils (EulerOS-SA-2023-1245)

high Nessus Plugin ID 170797

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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 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 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.(CVE-2021-42574 ) An out-of-bounds flaw was found in binutils stabs functionality. The attack needs to be initiated locally where an attacker could convince a victim to read a specially crafted file that is processed by objdump, leading to the disclosure of memory and possibly leading to the execution of arbitrary code or causing the utility to crash.(CVE-2021-45078) 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) The _bfd_XX_bfd_copy_private_bfd_data_common function in peXXigen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, processes a negative Data Directory size with an unbounded loop that increases the value of (external_IMAGE_DEBUG_DIRECTORY) *edd so that the address exceeds its own memory region, resulting in an out-of-bounds memory write, as demonstrated by objcopy copying private info with _bfd_pex64_bfd_copy_private_bfd_data_common in pex64igen.c.(CVE-2018-10534) 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)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization binutils security advisory.

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

Solution

Update the affected binutils packages.
