Key Security, Maintenance, and Features Releases

Security Based Updates

Kubernetes 1.26.2             
API Change:

  • A fix in the API avoids harmless (?) ".status.reservedFor: element 0: associative list without keys has an element that's a map type" errors in the apiserver. Validation now rejects the incorrect reuse of the same UID in different entries. (#115354, @pohly) [SIG API Machinery]             
    * usage of the pflag values in a normal Go flag set led to panics when printing the help message (#114680, @pohly) [SIG Instrumentation]           


  • Kubelet TCP and HTTP probes are more effective using networking resources: conntrack entries, sockets, ... This is achieved by reducing the TIME-WAIT state of the connection to 1 second, instead of the defaults 60 seconds. This allows kubelet to free the socket, and free conntrack entry and ephemeral port associated. (#115143, @aojea) [SIG Network and Node]   
  • Kubernetes is now built with Go 1.19.6 (#115833, @cpanato) [SIG Release and Testing]      
  • Use HorizontalPodAutoscaler v2 for kubectl (#114886, @a7i) [SIG CLI]           

Bug or Regression:     

  • Do not add DisruptionTarget condition by PodGC for pods which are in terminal phase (#115104, @mimowo) [SIG Apps and Testing]
  • Enforce nodeName cannot be set along with non-empty schedulingGates (#115636, @Huang-Wei) [SIG Apps and Scheduling]      
  • Fix a bug that caused to panic the apiserver when trying to allocate a Service with a dynamic ClusterIP and it has been configured with Service CIDRs with a /28 mask for IPv4 and a /124 mask for IPv6 (#115333, @aojea) [SIG Testing]  
  • Fix nil pointer error in nodevolumelimits csi logging (#115347, @sunnylovestiramisu) [SIG Scheduling]    
  • Fix the regression that introduced 34s timeout for DELETECOLLECTION calls (#115479, @tkashem) [SIG API Machinery]           
  • Fixed bug which caused the status of Indexed Jobs to only be updated when there are newly completed indexes. The completed indexes are now updated if the .status.completedIndexes has values outside of the [0, .spec.completions> range (#115462, @danielvegamyhre) [SIG Apps]         
  • Fixes bug in ValidatingAdmissionPolicy alpha which prevented policies from using a paramKind previously used by another policy (#115185, @alexzielenski) [SIG API Machinery]       
  • updates to v0.7.0 to fix CVE-2022-41723 (#115787, @liggitt) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]     
  • The Kubernetes API server now correctly detects and closes existing TLS connections when its client certificate file for kubelet authentication has been rotated. (#115566, @enj) [SIG API Machinery, Node and Testing]

Redis 7.0.9            
Upgrade urgency: SECURITY, contains fixes to security issues.  
Security Fixes:     

  • (CVE-2023-25155) Specially crafted SRANDMEMBER, ZRANDMEMBER, and HRANDFIELD commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process.   
  • (CVE-2022-36021) String matching commands (like SCAN or KEYS) with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to         hang and consume 100% CPU time. 

Bug Fixes:

  • Fix a crash when reaching the maximum invalidations limit of client-side tracking (#11814) 
  • Fix a crash when SPUBLISH is used after passing the cluster-link-sendbuf-limit (#11752)
  • Fix possible memory corruption in FLUSHALL when a client watches more than one key (#11854)   
  • Fix cluster inbound link keepalive time (#11785)          
  • Flush propagation list in active-expire of writable replicas to fix an assertion (#11615)    
  • Avoid propagating DEL of lazy expire from SCAN and RANDOMKEY as MULTI-EXEC (#11788)    

Performance and resource utilization improvements:    

  • Avoid realloc to reduce size of strings when it is unneeded (#11766) 
  • Improve CLUSTER SLOTS reply efficiency for non-continuous slots (#11745)

    resolve bugs and/or add new features. No existing interface method will be
