  script_tag(name:"insight", value:"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 resources

  - 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 'ssl_c_der' and 'ssl_f_der' to return DER
  formatted certs");
