Announcement ID: openSUSE-SU-2015:1831-1 Rating: important References: #937042 #937202 Cross-References: CVE-2015-3281 Affected Products: openSUSE 13.2 ______________________________________________________________________________

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
