Linux Distros Unpatched Vulnerability : CVE-2026-2739

medium Nessus Plugin ID 299679

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.

 - This affects versions of the package bn.js before 5.2.3. Calling maskn(0) on any BN instance corrupts the internal state, causing toString(), divmod(), and other methods to enter an infinite loop, hanging the process indefinitely. (CVE-2026-2739)

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

Solution

There is no known solution at this time.
