medium Nessus Plugin ID 182713

Language:

Synopsis

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

Description

The version of libxml2 installed on the remote host is prior to 2.9.1-6.6.43. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1841 advisory.

Xmlsoft Libxml2 v2.11.0 was discovered to contain a global buffer overflow via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. (CVE-2023-39615)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update libxml2' to update your system.
