   feature is now available.

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.
