Amazon Linux 2022 : (ALAS2022-2022-204)

high Nessus Plugin ID 167000


The remote Amazon Linux 2022 host is missing a security update.


It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-204 advisory.

- In cifs-utils through 6.14, a stack-based buffer overflow when parsing the mount.cifs ip= command-line argument could lead to local attackers gaining root privileges. (CVE-2022-27239)

- cifs-utils through 6.14, with verbose logging, can cause an information leak when a file contains = (equal sign) characters but is not a valid credentials file. (CVE-2022-29869)

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


Run 'dnf update cifs-utils --releasever=2022.0.20221102' to update your system.
