CVE-2016-5420 (opens in a new tab)How to fix?
Upgrade Alpine:3.18 curl to version 7.50.1-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Alpine.
See How to fix? for Alpine:3.18 relevant fixed versions and status.
curl and libcurl before 7.50.1 do not check the client certificate when choosing the TLS connection to reuse, which might allow remote attackers to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.
