Amazon Linux 2 : xerces-c (ALAS-2020-1415)

high Nessus Plugin ID 135933

Language:

Synopsis

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

Description

The version of xerces-c installed on the remote host is prior to 3.1.1-10. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1415 advisory.

 A use-after-free vulnerability was found in xerces-c in the way an XML document is processed via the SAX API. Applications that process XML documents with an external Document Type Definition (DTD) may be vulnerable to this flaw. A remote attacker could exploit this flaw by creating a specially crafted XML file that would crash the application or potentially lead to arbitrary code execution. (CVE-2018-1311)

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 xerces-c' to update your system.
