Alpine: curl: security update to 7.66.0-r4

low Tenable Cloud Security Plugin ID 403995

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2021-22898)
