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.

SynopsisThe remote Ubuntu host is missing a security update.
DescriptionThe remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-4520-1 advisory.
- sa-exim 4.2.1 allows attackers to execute arbitrary code if they can write a .cf file or a rule. This occurs because Greylisting.pm relies on eval (rather than direct parsing and/or use of the taint feature).
This issue is similar to CVE-2018-11805. (CVE-2019-19920)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpdate the affected sa-exim package.
