Description Aaron W. Swenson gentoo-dev 2021-07-05 10:13:11 UTC
From the Fossil Forums:
It has been discovered that the client-side TLS implementation in Fossil was often failing to verify that the hostname of the server matched the hostname contained in the TLS certificate. Hence, an "https" connection would always work as long as the server returned any valid certificate, even if that certificate did not match the hostname.

Missed a couple fixes introduced in previous commits. use binding := for dev-libs/openssl in commit 12b8e1427c7b1b79a5f05f779c05f1c0dc1244d1 and fix BadDefaultUseFlags commit 74b6fd7b43d1233e481f394f3bacce23475de724.

So, please stabilize the following target(s):
