Echo: curl-7.69.1: security update to 7.69.1+e1

medium Tenable Self-Hosted Container Security Plugin ID 476238

Description

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

 - curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the
 code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected
 cipher set was stored in a single "static" variable in the library, which has the surprising side-effect
 that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will
 accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport
 security significantly. (CVE-2021-22897)

Solution

Update the curl-7.69.1 library and its related packages to version 7.69.1+e1 or later.
