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
