Sendmail < 8.14.9 close-on-exec SMTP Connection Manipulation

low Nessus Plugin ID 74289
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote mail server is affected by an SMTP connection manipulation vulnerability.


The remote mail server is running a version of Sendmail prior to 8.14.9. It is, therefore, affected by a flaw related to file descriptors and the 'close-on-exec' flag that may allow a local attacker to cause unspecified impact on open SMTP connections.


Upgrade to Sendmail 8.14.9 or later.
