[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:
    https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-16869
  (* Security fix *)
