Echo: libsoup3: security update to 3.6.5-6

high Tenable Self-Hosted Container Security Plugin ID 465784

Description

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

 - A flaw was found in the asynchronous message queue handling of the libsoup library, widely used by GNOME
 and WebKit-based applications to manage HTTP/2 communications. When network operations are aborted at
 specific timing intervals, an internal message queue item may be freed twice due to missing state
 synchronization. This leads to a use-after-free memory access, potentially crashing the affected
 application. Attackers could exploit this behavior remotely by triggering specific HTTP/2 read and cancel
 sequences, resulting in a denial-of-service condition. (CVE-2025-12105)

Solution

Update the libsoup3 library and its related packages to version 3.6.5-6 or later.
