Azure Linux 3.0 Security Update: libxml2 (CVE-2025-32415)

high Nessus Plugin ID 241901

Language:

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of libxml2 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-32415 advisory.

 - 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)

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

Solution

Update the affected packages.
