- Apply "openssl-CVE-2024-4741.patch" to fix a use-after-free
  security vulnerability. Calling the function SSL_free_buffers()
  potentially caused memory to be accessed that was previously
  freed in some situations and a malicious attacker could attempt
  to engineer a stituation where this occurs to facilitate a
  denial-of-service attack. [CVE-2024-4741, bsc#1225551]
