Echo: xerces-c-3.2.3: security update to 3.2.3+e1

critical Tenable Self-Hosted Container Security Plugin ID 476430

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the xerces-c-3.2.3 library and its related packages to version 3.2.3+e1 or later.
