Description Agostino Sarubbo gentoo-dev 2016-08-25 09:26:17 UTC
From ${URL} :

It was found that if a ticket callback changes the HMAC digest to SHA512 the existing sanity checks are 
not sufficient and an attacker could perform a DoS attack with a malformed ticket.

Upstream patch:

https://github.com/openssl/openssl/commit/1bbe48ab149893a78bf99c8eb8895c928900a16f


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
