FreeBSD : LibreSSL -- TLS verification vulnerability (24673ed7-2bf3-11e7-b291-b499baebfeaf)

Low Nessus Plugin ID 99749


The remote FreeBSD host is missing one or more security-related updates.


Jakub Jirutka reports :

LibreSSL 2.5.1 to 2.5.3 lacks TLS certificate verification if SSL_get_verify_result is relied upon for a later check of a verification result, in a use case where a user-provided verification callback returns 1, as demonstrated by acceptance of invalid certificates by nginx.


Update the affected packages.
