Amazon Linux 2 : xerces-c (ALAS-2024-2476)

critical Nessus Plugin ID 191519

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 ALAS2-2024-2476 advisory.

- The Apache Xerces C++ XML parser on versions 3.0.0 before 3.2.5 contains a use-after-free error triggered during the scanning of external DTDs. Users are recommended to upgrade to version 3.2.5 which fixes the issue, or mitigate the issue by disabling DTD processing. This can be accomplished via the DOM using a standard parser feature, or via SAX using the XERCES_DISABLE_DTD environment variable. This issue has been disclosed before as CVE-2018-1311, but unfortunately that advisory incorrectly stated the issue would be fixed in version 3.2.3 or 3.2.4. (CVE-2024-23807)

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.
