Echo: glib-networking: security update to 2.80.1-1+e2

high Tenable Cloud Security Plugin ID 478109

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in glib-networking. When establishing connections using Transport Layer Security (TLS)
 version 1.3, the client-side session cache does not limit the number of session tickets retained for a
 single host. A malicious server can exploit this by sending excessive session ticket messages, causing the
 client application to continuously consume memory. This unbounded memory growth can exhaust system memory,
 resulting in a Denial of Service (DoS). (CVE-2026-103963)

Solution

Update the glib-networking library and its related packages to version 2.80.1-1+e2 or later.
