Description GLSAMaker/CVETool Bot gentoo-dev 2017-04-27 18:44:57 UTC
CVE-2017-8301 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-8301):
  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.

FYI, libressl released portable version 2.5.4 yesterday, which contains a fix for this CVE, as per the Github issue linked in comment 1.
