23          instead.

28          the check for libsocket to have them found on Solaris
29        * Fix IPv4-only bug in bind_addr use in retry_connect()
30        * Add more debug code in connect_port()
31
323.1.5 (26-03-2015):

36        * Add command line option '--server-host' to set the log server
37        * In samhain.startLinux.in start script template, add code to read

59          overflow [CVE-2014-4607,LMS-2014-06-16-1] is irrelevant anyway
60          because the function is never used on external data).
61        * Fixed a minor bug in exepack_fill.c that was unearthed by the minilzo
62          overflow check (the required buffer length information for the check
63          wasn't provided)

102          by isquish)
