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

medium Tenable Cloud Security Plugin ID 473636

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 gst_avi_demux_riff_parse_vprp(), the number
 of available gst_riff_vprp_video_field_desc entries is calculated by dividing the remaining buffer size by
 the attacker-controlled vprp->fields value, rather than by sizeof(gst_riff_vprp_video_field_desc). This
 can cause the parser to treat more field descriptors as available than fit in the input buffer, resulting
 in out-of-bounds reads. Processing a crafted AVI via playbin/decodebin can crash the application (denial
 of service). Fixed upstream in gst-plugins-good 1.28.6 (GStreamer-SA-2026-0072). (CVE-2026-73434)

Solution

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