Echo: gst-plugins-good1.0: security update to 1.26.2-1+e8

medium Tenable Cloud Security Plugin ID 478630

Description

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

 - A flaw was found in GStreamer gst-plugins-good (avidemux). In the subindex parser, missing validation of
 the entry count can cause excessive memory allocation and denial of service. Because avidemux is auto-
 plugged by playbin, decodebin, and gst-discoverer, opening or previewing a crafted AVI is sufficient to
 trigger the issue. Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072). (CVE-2026-73473)

Solution

Update the gst-plugins-good1.0 library and its related packages to version 1.26.2-1+e8 or later.
