Azure Linux 3.0 Security Update: libxml2 (CVE-2024-56171)

high Nessus Plugin ID 233136

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-2024-56171 advisory.

 - libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a use-after-free in xmlSchemaIDCFillNodeTables and xmlSchemaBubbleIDCNodeTables in xmlschemas.c. 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-2024-56171)

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.
