TencentOS Server 4: gstreamer1-plugins-base (TSSA-2025:0674)

medium Nessus Plugin ID 258020

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0674 advisory.

 Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

 CVE-2025-47808:
 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-2025-47807:
 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-2025-47806:
 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.

Tenable has extracted the preceding description block directly from the Tencent Linux 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

Update the affected packages.
