TITLE

Perl Out-of-bounds write vulnerability in

DESCRIPTION

Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow. Perl Is vulnerable to out-of-bounds writes.Information is tampered with and service operation is interrupted (DoS) It may be put into a state. An attacker could exploit this vulnerability to cause a denial of service. Description: Red Hat Advanced Cluster Management for Kubernetes 2.2.4 images Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console—with security policy built in. See the following Release Notes documentation, which will be updated shortly for this release, for additional details about this release: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_mana gement_for_kubernetes/2.2/html/release_notes/ Security fixes: * redisgraph-tls: redis: integer overflow when configurable limit for maximum supported bulk input size is too big on 32-bit platforms (CVE-2021-21309) * console-header-container: nodejs-netmask: improper input validation of octal input data (CVE-2021-28092) * console-container: nodejs-is-svg: ReDoS via malicious string (CVE-2021-28918) Bug fixes: * RHACM 2.2.4 images (BZ# 1957254) * Enabling observability for OpenShift Container Storage with RHACM 2.2 on OCP 4.7 (BZ#1950832) * ACM Operator should support using the default route TLS (BZ# 1955270) * The scrolling bar for search filter does not work properly (BZ# 1956852) * Limits on Length of MultiClusterObservability Resource Name (BZ# 1959426) * The proxy setup in install-config.yaml is not worked when IPI installing with RHACM (BZ# 1960181) * Unable to make SSH connection to a Bitbucket server (BZ# 1966513) * Observability Thanos store shard crashing - cannot unmarshall DNS message (BZ# 1967890) 3.
