Sendmail < 8.12.10 prescan() Function Remote Overflow

critical Nessus Plugin ID 11838
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 prone to multiple buffer overflow attacks.


According to its version number, the remote Sendmail server is between 5.79 to 8.12.9. Such versions are reportedly vulnerable to remote buffer overflow attacks, one in the 'prescan()' function and another involving its ruleset processing. A remote user may be able to leverage these issues to gain root privileges.


Upgrade to Sendmail version 8.12.10 or later.
