openSUSE Security Update : haproxy (openSUSE-2015-682)

medium Nessus Plugin ID 86623

Language:

Synopsis

The remote openSUSE host is missing a security update.

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

Solution

Update the affected haproxy packages.
