Linux Distros Unpatched Vulnerability : CVE-2025-61729

high Nessus Plugin ID 277083

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.

 - Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption. (CVE-2025-61729)

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

Solution

There is no known solution at this time.
