Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1184 advisory.

 In GStreamer through 1.26.1, the subparse plugin's parse_subrip_time function may write data past the bounds of a stack buffer, leading to a crash. (CVE-2025-47806)

 In GStreamer through 1.26.1, the subparse plugin's subrip_unescape_formatting function may dereference a NULL pointer while parsing a subtitle file, leading to a crash. (CVE-2025-47807)

 In GStreamer through 1.26.1, the subparse plugin's tmplayer_parse_line function may dereference a NULL pointer while parsing a subtitle file, leading to a crash. (CVE-2025-47808)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update gstreamer1-plugins-base --releasever 2023.8.20250915' or or 'dnf update --advisory ALAS2023-2025-1184 --releasever 2023.8.20250915' to update your system.
