Description:

The Custom Metrics Autoscaler Operator for Red Hat OpenShift is an optional operator, based on the Kubernetes Event Driven Autoscaler (KEDA), which allows workloads to be scaled using additional metrics sources other than pod metrics. This release builds upon updated compiler, runtime library, and base images for the purpose of resolving any potential security issues present in previous toolset versions.

This version makes use of newer tools and libraries to address the following issues:  
golang: net/http/internal: Denial of Service (DoS) via Resource Consumption via HTTP requests (CVE-2023-39326)  
jose-go: improper handling of highly compressed data (CVE-2024-28180)  
opentelemetry-go-contrib: DoS vulnerability in otelgrpc due to unbound cardinality metrics (CVE-2023-47108)

In addition, the following bug has been fixed:  
Custom metrics operator memory leak when invalid scaledObject is defined (prometheus scaler)

This release is based upon KEDA 2.12.1

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.Description:The unbound packages provide a validating, recursive, and caching DNS or DNSSEC resolver. Security Fix(es):* bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)* bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)Security Fix(es):* A vulnerability was found in Unbound due to incorrect default permissions,allowing any process outside the unbound group to modify the unbound runtimeconfiguration. The default combination of the \"control-use-cert: no\" option witheither explicit or implicit use of an IP address in the \"control-interface\"option could allow improper access. If a process can connect over localhost toport 8953, it can alter the configuration of unbound.service. This flaw allowsan unprivileged local process to manipulate a running instance, potentiallyaltering forwarders, allowing them to track all queries forwarded by the localresolver, and, in some cases, disrupting resolving altogether.To mitigate the vulnerability, a new file\"/etc/unbound/conf.d/remote-control.conf\" has been added and included in themain unbound configuration file, \"unbound.conf\". The file contains twodirectives that should limit access to unbound.conf:    control-interface: \"/run/unbound/control\"    control-use-cert: \"yes\"For details about these directives, run \"man unbound.conf\".Updating to the version of unbound provided by this advisory should, in mostcases, address the vulnerability. To verify that your configuration is notvulnerable, use the \"unbound-control status | grep control\" command. If theoutput contains \"control(ssl)\" or \"control(namedpipe)\", your configuration isnot vulnerable. If the command output returns only \"control\", the configurationis vulnerable because it does not enforce access only to the unbound groupmembers. To fix your configuration, add the line \"include:/etc/unbound/conf.d/remote-control.conf\" to the end of the file\"/etc/unbound/unbound.conf\". If you use a custom\"/etc/unbound/conf.d/remote-control.conf\" file, add the new directives to thisfile. (CVE-2024-1488)For more details about the security issue(s), including the impact, a CVSSscore, acknowledgments, and other related information, refer to the CVE page(s)listed in the References section.Solution:https://access.redhat.com/articles/11258CVEs:CVE-2023-50387References:https://access.redhat.com/security/updates/classification/#importanthttps://bugzilla.redhat.com/show_bug.cgi?id=2263914https://bugzilla.redhat.com/show_bug.cgi?id=2263917https://bugzilla.redhat.com/show_bug.cgi?id=2264183

Issue date:         2024-04-15  
Revision:           03  
CVE Names:          CVE-2023-4408  
====================================================================

Summary: 

Updates for bind and bind-dyndb-ldap are now available for Red Hat Enterprise Linux 9.2 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description:

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Bind-dyndb-ldap provides an LDAP back-end plug-in for BIND. It features support for dynamic updates and internal caching, to lift the load off of your LDAP server.

Security Fix(es):

* bind9: Parsing large DNS messages may cause excessive CPU load (CVE-2023-4408)

* bind9: Querying RFC 1918 reverse zones may cause an assertion failure when \"nxdomain-redirect\" is enabled (CVE-2023-5517)

* bind9: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution (CVE-2023-5679)

* bind9: Specific recursive query patterns may lead to an out-of-memory condition (CVE-2023-6516)

* bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator (CVE-2023-50387)

* bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources (CVE-2023-50868)

Red Hat Security Advisory 2024-1803-03

Red Hat Security Advisory 2024-1802-03 - An update for unbound is now available for Red Hat Enterprise Linux 8.8 Extended Update Support.

    The following advisory data is extracted from:https://access.redhat.com/security/data/csaf/v2/advisories/2024/rhsa-2024_1802.jsonRed Hat officially shut down their mailing list notifications October 10, 2023.  Due to this, Packet Storm has recreated the below data as a reference point to raise awareness.  It must be noted that due to an inability to easily track revision updates without crawling Red Hat's archive, these advisories are single notifications and we strongly suggest that you visit the Red Hat provided links to ensure you have the latest information available if the subject matter listed pertains to your environment.- Packet Storm Staff====================================================================Red Hat Security AdvisorySynopsis:           Important: unbound security updateAdvisory ID:        RHSA-2024:1802-03Product:            Red Hat Enterprise LinuxAdvisory URL:       https://access.redhat.com/errata/RHSA-2024:1802Issue date:         2024-04-15Revision:           03CVE Names:          CVE-2024-1488====================================================================Summary: An update for unbound is now available for Red Hat Enterprise Linux 8.8 Extended Update Support.Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.Description:The unbound packages provide a validating, recursive, and caching DNS or DNSSEC resolver. Security Fix(es):* A vulnerability was found in Unbound due to incorrect default permissions,allowing any process outside the unbound group to modify the unbound runtimeconfiguration. The default combination of the \"control-use-cert: no\" option witheither explicit or implicit use of an IP address in the \"control-interface\"option could allow improper access. If a process can connect over localhost toport 8953, it can alter the configuration of unbound.service. This flaw allowsan unprivileged local process to manipulate a running instance, potentiallyaltering forwarders, allowing them to track all queries forwarded by the localresolver, and, in some cases, disrupting resolving altogether.To mitigate the vulnerability, a new file\"/etc/unbound/conf.d/remote-control.conf\" has been added and included in themain unbound configuration file, \"unbound.conf\". The file contains twodirectives that should limit access to unbound.conf:    control-interface: \"/run/unbound/control\"    control-use-cert: \"yes\"For details about these directives, run \"man unbound.conf\".Updating to the version of unbound provided by this advisory should, in mostcases, address the vulnerability. To verify that your configuration is notvulnerable, use the \"unbound-control status | grep control\" command. If theoutput contains \"control(ssl)\" or \"control(namedpipe)\", your configuration isnot vulnerable. If the command output returns only \"control\", the configurationis vulnerable because it does not enforce access only to the unbound groupmembers.

If you use a custom\"/etc/unbound/conf.d/remote-control.conf\" file, add the new directives to thisfile.
