File size: 104.2 KB
RevLine 
[475]13.1.6:
[476]2        * More modern and more complete VA_COPY autoconf macro
3          (from the openwrt project)
[474]4        * Modify testcompile.sh to remove 'smatch' and use 'clang'
5          instead.
6        * Fix compile problems with clang.
[473]7        * Modify testcompile.sh to remove 'uno' and use 'cppcheck'
8          for static checking

10          the check for libsocket to have them found on Solaris
11        * Fix IPv4-only bug in bind_addr use in retry_connect()
12        * Add more debug code in connect_port()
13
[475]143.1.5 (26-03-2015):
[469]15        * Fix IPv6 issue with portcheck (need to be able to specify
16          IPv6 interfaces).
17        * Fix minor issues with bugs in testing code
18        * Add command line option '--server-host' to set the log server
19        * In samhain.startLinux.in start script template, add code to read
20          options from /etc/sysconfig/${NAME} for RedHat
21
223.1.4 (17-02-2015):
[463]23        * Add non-existent file to the regression test config
24        * Fix erroneous call to sh_hash_init when a missing file
25          is specified in the configuration
26        * Fix buffer allocation for getgrnam_r for large groups
[462]27          (problem reported by Sergio B)
[463]28        * Search RPM in $HOME/rpmbuild if test -d _topdir fails (CentOS
[461]29          recommends '%(echo $HOME)/topdir', reported by E. Taft)
30
[462]313.1.3 (01-11-2014):
[463]32        * Remove initgroups() from the popen call in unix entropy gatherer

38        * Allow multiple exclusions for SUID check
39        * Use calloc instead of malloc
[456]40        * Add overflow check in minilzo.c (but the potential integer
41          overflow [CVE-2014-4607,LMS-2014-06-16-1] is irrelevant anyway
42          because the function is never used on external data).
43        * Fixed a minor bug in exepack_fill.c that was unearthed by the minilzo
44          overflow check (the required buffer length information for the check
45          wasn't provided)
[457]46        * Fixed incorrect logic in setting the ALLIGNORE flag (more specific
47          directory / file directives were ignored)

[458]49          directory) and #359 (reporting of deleted/added top level directory)
[459]50        * Fix a free() on NULL (harmless but avoids spurious warning)
[454]51

[440]65        * Fixes for Ubuntu 13.4:
[442]66          - no error msg for failing stat on /run/user/Username/gvfs in
[441]67            suidcheck
68          - no error message for failing hardlink check on /run/user/Username
