TITLE

libxml2  Infinite loop vulnerability in

DESCRIPTION

xmlStringLenDecodeEntities in parser.c in libxml2 2.9.10 has an infinite loop in a certain end-of-file situation. There is a security vulnerability in the xmlStringLenDecodeEntities of the parser.c file in libxml2 version 2.9.10. It exists that libxml2 incorrectly handled certain XML files. (CVE-2019-19956, CVE-2020-7595). Description: Red Hat OpenShift Container Storage is software-defined storage integrated with and optimized for the Red Hat OpenShift Container Platform. Red Hat OpenShift Container Storage is a highly scalable, production-grade persistent storage for stateful applications running in the Red Hat OpenShift Container Platform. In addition to persistent storage, Red Hat OpenShift Container Storage provisions a multicloud data management service with an S3 compatible API. These updated images include numerous security fixes, bug fixes, and enhancements. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
