  Update 91:

  - OpenSSL security vulnerabilities: There are six security vulnerabilities that are fixed in
  version 1.0.2b of openssl. This version contained an ABI breakage bug that required us to wait
  for a fix for that and rebuild this Core Update.

  Among these are fixes for the Logjam vulnerability and others that are filed under CVE-2015-1788,
  CVE-2015-1789, CVE-2015-1790, CVE-2015-1792, CVE-2015-1791, and CVE-2014-8176.

  - StrongSwan IPsec security vulnerability: In strongSwan 5.3.1, a security vulnerability that is
  filed under CVE-2015-3991 was fixed. A denial-of-service and potential code execution was possible
  with specially crafted IKE messages.

  - IPFire ships now version 5.3.2 which fixes a second vulnerability (CVE-2015-4171).");
