CentOS 8 : sudo (CESA-2024:0811)

high Nessus Plugin ID 190850

Language:

Synopsis

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

Description

The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2024:0811 advisory.

 - Sudo before 1.9.13 does not escape control characters in log messages. (CVE-2023-28486)

 - Sudo before 1.9.13 does not escape control characters in sudoreplay output. (CVE-2023-28487)

 - Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value), and because the values do not resist flips of a single bit. (CVE-2023-42465)

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 sudo package.
