Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5459-1 advisory.

Aurlien Aptel discovered that cifs-utils invoked a shell when requesting a password. In certain environments, a local attacker could possibly use this issue to escalate privileges. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-14342)

It was discovered that cifs-utils incorrectly used host credentials when mounting a krb5 CIFS file system from within a container. An attacker inside a container could possibly use this issue to obtain access to sensitive information. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2021-20208)

It was discovered that cifs-utils incorrectly handled certain command-line arguments. A local attacker could possibly use this issue to obtain root privileges. (CVE-2022-27239)

It was discovered that cifs-utils incorrectly handled verbose logging. A local attacker could possibly use this issue to obtain sensitive information. (CVE-2022-29869)
