TencentOS Server 2: expat (TSSA-2025:0543)

high Nessus Plugin ID 247821

Synopsis

The remote TencentOS Server 2 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0543 advisory.

Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

CVE-2017-9233:
XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD.

CVE-2016-9063:
An integer overflow during the parsing of XML using the Expat library. This vulnerability affects Firefox < 50.

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.
