Amazon Linux 2 : libxml2 (ALAS-2025-2860)

high Nessus Plugin ID 237474

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of libxml2 installed on the remote host is prior to 2.9.1-6. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2860 advisory.

In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters. (CVE-2025-32414)

In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap- based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used. (CVE-2025-32415)

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 'yum update libxml2' to update your system.
