GNU Binutils before 2.34 has an uninitialized-heap vulnerability in function tic4x_print_cond (file opcodes/tic4x-dis.c) which could allow attackers to make an information leak.

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

  - An issue was discovered in GNU Binutils 2.34. It is a memory leak when process microblaze-dis.c. This one     will consume memory on each insn disassembled. (CVE-2020-21490)

  - GNU Binutils before 2.34 has an uninitialized-heap vulnerability in function tic4x_print_cond (file     opcodes/tic4x-dis.c) which could allow attackers to make an information leak. (CVE-2020-35342)

  - GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the     function bfd_dwarf2_find_nearest_line_with_alt at dwarf2.c. The attacker could supply a crafted ELF file     and cause a DNS attack. (CVE-2022-48064)

  - GNU Binutils before 2.40 was discovered to contain a memory leak vulnerability var the function     find_abstract_instance in dwarf2.c. (CVE-2022-48065)

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 Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6381-1 advisory.

    It was discovered that a memory leak existed in certain GNU binutils modules. An attacker could possibly     use this issue to cause a denial of service (memory exhaustion). (CVE-2020-19724, CVE-2020-21490)

    It was discovered that GNU binutils was not properly performing bounds checks in several functions, which     could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service,     expose sensitive information or execute arbitrary code. (CVE-2020-19726, CVE-2021-46174, CVE-2022-45703)

    It was discovered that GNU binutils was not properly initializing heap memory when processing certain     print instructions. An attacker could possibly use this issue to expose sensitive information.
    (CVE-2020-35342)

    It was discovered that GNU binutils was not properly handling the logic behind certain memory management     related operations, which could lead to a buffer overflow. An attacker could possibly use this issue to     cause a denial of service or execute arbitrary code. (CVE-2022-44840)

    It was discovered that GNU binutils was not properly handling the logic behind certain memory management     related operations, which could lead to an invalid memory access. An attacker could possibly use this     issue to cause a denial of service. (CVE-2022-47695)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

An update of the binutils package has been released.
