Ubuntu 16.04 ESM / 18.04 ESM : GNU binutils vulnerabilities (USN-6381-1)

high Nessus Plugin ID 181560

Language:

Synopsis

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

Description

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.

Solution

Update the affected packages.
