New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.6
Synopsis
The remote Amazon Linux AMI host is missing a security update.
Description
The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1452 advisory.
- All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with log level = 3 (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange.
In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). (CVE-2019-14907)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Run 'yum update samba' to update your system.
