[slackware-security] nettle (SSA:2018-339-02)

New nettle packages are available for Slackware 14.2 and -current to
fix security issues.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
This update fixes a security issue:
A Bleichenbacher type side-channel based padding oracle attack was found
in the way nettle handles endian conversion of RSA decrypted PKCS#1 v1.5
data. An attacker who is able to run a process on the same physical core
as the victim process, could use this flaw to extract plaintext or in some
cases downgrade any TLS connections to a vulnerable server.
For more information, see:

(* Security fix *)
