Linux Distros Unpatched Vulnerability : CVE-2025-6052

high Nessus Plugin ID 258244

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 how GLib's GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn't. As a result, data may be written past the end of the allocated memory, leading to crashes or memory corruption. (CVE-2025-6052)

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

Solution

There is no known solution at this time.
