Security update for curl

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.

Описание

curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.
