Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - Icinga 2 is an open source monitoring system. From 2.10.0 to before 2.15.1, 2.14.7, and 2.13.13, the safe- reload script (also used during systemctl reload icinga2) and logrotate configuration shipped with Icinga 2 read the PID of the main Icinga 2 process from a PID file writable by the daemon user, but send the signal as the root user. This can allow the Icinga user to send signals to processes it would otherwise not permitted to. A fix is included in the following Icinga 2 versions: 2.15.1, 2.14.7, and 2.13.13.
 (CVE-2025-61909)

Note that Nessus relies on the presence of the package as reported by the vendor.
