"The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the
openSUSE-SU-2022:0503-1 advisory.

  - There's a vulnerability within the Apache Xerces Java (XercesJ) XML parser when handling specially crafted
    XML document payloads. This causes, the XercesJ XML parser to wait in an infinite loop, which may
    sometimes consume system resources for prolonged duration. This vulnerability is present within XercesJ
    version 2.12.1 and the previous versions. (CVE-2022-23437)

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