Linux Distros Unpatched Vulnerability : CVE-2026-1484

medium Nessus Plugin ID 296776

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.

 - A flaw was found in the GLib Base64 encoding routine when processing very large input data. Due to incorrect use of integer types during length calculation, the library may miscalculate buffer boundaries.
 This can cause memory writes outside the allocated buffer. Applications that process untrusted or extremely large Base64 input using GLib may crash or behave unpredictably. (CVE-2026-1484)

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

Solution

There is no known solution at this time.
