[slackware-security]  libgcrypt (SSA:2016-236-02)

New libgcrypt packages are available for Slackware 13.0, 13.1, 13.37, 14.0,
14.1, 14.2, and -current to fix a security issue.

Here are the details from the Slackware 14.2 ChangeLog:
patches/packages/libgcrypt-1.7.3-i586-1_slack14.2.txz:  Upgraded.
  Fix critical security bug in the RNG [CVE-2016-6313].  An attacker who
  obtains 580 bytes from the standard RNG can trivially predict the next
  20 bytes of output.  (This is according to the NEWS file included in the
  source.  According to the annoucement linked below, an attacker who obtains
  4640 bits from the RNG can trivially predict the next 160 bits of output.)
  Problem detected by Felix Doerre and Vladimir Klebanov, KIT.
  For more information, see:
  (* Security fix *)
