   An update that solves one vulnerability and has one errata
   is now available.

Description:

   haproxy was updated to fix two security issues.

   These security issues were fixed:
   - CVE-2015-3281: The buffer_slow_realign function in HAProxy did not
     properly realign a buffer that is used for pending outgoing data, which
     allowed remote attackers to obtain sensitive information (uninitialized
     memory contents of previous requests) via a crafted request (bsc#937042).
   - Changed DH parameters to prevent Logjam attack.

   These non-security issues were fixed:
   - BUG/MAJOR: buffers: make the buffer_slow_realign() function respect
     output data
   - BUG/MINOR: ssl: fix smp_fetch_ssl_fc_session_id
   - MEDIUM: ssl: replace standards DH groups with custom ones
   - BUG/MEDIUM: ssl: fix tune.ssl.default-dh-param value being overwritten
   - MINOR: ssl: add a destructor to free allocated SSL ressources
   - BUG/MINOR: ssl: Display correct filename in error message
   - MINOR: ssl: load certificates in alphabetical order
   - BUG/MEDIUM: checks: fix conflicts between agent checks and ssl
     healthchecks
   - BUG/MEDIUM: ssl: force a full GC in case of memory shortage
   - BUG/MEDIUM: ssl: fix bad ssl context init can cause segfault in case of
     OOM.
   - BUG/MINOR: ssl: correctly initialize ssl ctx for invalid certificates
   - MINOR: ssl: add statement to force some ssl options in global.
   - MINOR: ssl: add fetchs 'ssl_c_der' and 'ssl_f_der' to return DER
     formatted certs
