Rocky Linux 9.6 [TuxCare] Security Update: gstreamer1-plugins-good / gstreamer1-plugins-good-gtk / etc Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1792572593)

critical Nessus Plugin ID 369518

Synopsis

The Rocky Linux host is missing one or more security updates.

Description

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1792572593 advisory.

- An incomplete fix for CVE-2024-47778 allows an out-of-bounds read in gst_wavparse_adtl_chunk() function.
The patch added a size validation check lsize + 8 > size, but it does not account for the GST_ROUND_UP_2(lsize) used in the actual offset calculation. When lsize is an odd number, the parser advances more bytes than validated, causing OOB read. (CVE-2026-1940)

- An issue was discovered in GStreamer gst-plugins-good before 1.28.2. When parsing MP4 audio tracks, the isomp4 plugin's qtdemux_parse_trak function does not sufficiently validate atom data before performing division operations, leading to denial of service due to integer division by zero. (CVE-2026-46469)

- An issue was discovered in GStreamer gst-plugins-good before 1.28.2. When parsing MP4 audio tracks, the isomp4 plugin's qtdemux_audio_caps function does not sufficiently validate atom data before performing division operations, leading to denial of service due to integer division by zero. (CVE-2026-46470)

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

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1792572593.
