Summary

The remote host is missing an update for the Huawei EulerOS 'curl' package(s) announced via the EulerOS-SA-2021-1962 advisory.

Insight

Insight

A flaw was found in the way libcurl handled TLS 1.3 session tickets. A malicious HTTPS proxy could possibly use this flaw to make libcurl resume a TLS session it previously had with the proxy while intending to resume a TLS session with a target server, making it possible for the proxy to perform a man-in-the-middle attack.(CVE-2021-22890) It was discovered that libcurl did not remove authentication credentials from URLs when automatically populating the Referer HTTP request header while handling HTTP redirects. This could lead to exposure of the credentials to the server to which requests were redirected.(CVE-2021-22876)
