An update that solves one vulnerability and contains one feature can now be installed.

Description:

This update for curl fixes the following issues:

  • CVE-2021-22898: Fixed curl TELNET stack contents disclosure (bsc#1186114).
  • Allow partial chain verification [jsc#SLE-17956]
  • Have intermediate certificates in the trust store be treated as trust-anchors, in the same way as self-signed root CA certificates are. This allows users to verify servers using the intermediate cert only, instead of needing the whole chain.
  • Set FLAG_TRUSTED_FIRST unconditionally.
  • Do not check partial chains with CRL check.
