Fixed bugs and common vulnerabilities in the 23.02 release 

The 23.02 release includes updates to mitigate against the following Common Vulnerabilities and Exposures (CVEs): 

  •  CVE-2022-37434 zlib 

  •  CVE-2018-25032 zlib 

The 23.02 release also includes bug fixes for the following behaviors: 

  • Wiznet W5500 data dropouts when connected with a 100BaseTX connection are addressed, and overall performance has increased by up to 2x. 

  • An AF_UNSPEC behavior change when using mDNS introduced in the 22.11 OS has been reverted. 

 

New and updated samples, code snippets, and Gallery projects 

The 23.02 release of the Azure Sphere samples, code snippets, and Gallery projects includes the following changes: 

Unicast DNS Service Discovery Gallery project 

The Unicast DNS service discovery gallery project demonstrates how to perform DNS service discovery by sending DNS-SD queries to a configured DNS server. Unlike multicast service discovery, this mechanism can be used to dynamically open access to not only local, but also remote endpoints in the device firewall at runtime.
