MiracleLinux 8 : gstreamer1-plugins-good-1.16.1-7.el8_10.8 (AXBA:2026-1806:08)

medium Nessus Plugin ID 344584

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 8 host has packages installed that are affected by a vulnerability as referenced in the AXBA:2026-1806:08 advisory.

 - A flaw was found in GStreamer gst-plugins-good (avidemux). When parsing FUJIFILM metadata in an AVI strd chunk, gst_avi_demux_parse_strd() decrements a remaining-length counter by fixed offsets (98 and 10 bytes) without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 bytes, the counter underflows to a very large unsigned value, causing subsequent null-terminated string scanning to read far beyond the allocated heap buffer. Date-format normalization may also write beyond the buffer end.
 Confirmed impacts include heap out-of-bounds read, out-of-bounds write, heap information disclosure (adjacent data appearing in parsed metadata), and application crash/denial of service. The avidemux element is auto-plugged by playbin, decodebin, and gst-discoverer, so 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-2026-73433)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected gstreamer1-plugins-good and / or gstreamer1-plugins-good-gtk packages.
