NVD Description

Note: Versions mentioned in the description apply only to the upstream satellite/iop-vulnerability-frontend-rhel9 package and not the satellite/iop-vulnerability-frontend-rhel9 package as distributed by RHEL.

fast-xml-parser allows users to validate XML, parse XML to JS object, or build XML from JS object without C/C++ based libraries and no callback. In versions 4.1.3 through 5.3.5, the XML parser can be forced to do an unlimited amount of entity expansion. With a very small XML input, it’s possible to make the parser spend seconds or even minutes processing a single request, effectively freezing the application. Version 5.3.6 fixes the issue. As a workaround, avoid using DOCTYPE parsing by processEntities: false option.
