Bug #1443
Updated by Victor Julien over 9 years ago
Hello All,
In reviewing source code in Suricata-2.0.6, in directory
'libhtp/test', file 'test.c', I found an instance where a call
to malloc() is made, without a check for a return value of NULL
which indicates failure. The patch file below corrects this
issue:

In directory 'src', file 'detect-dce-opnum.c', there are some instances
of the deprecated function call index(), which according to posix
standards, should be replaced by 'strchr()'. The patch file below

In directory 'src', file 'util-radix-tree.c', there are some instances
of the deprecated function call bzero(), which according to posix
standards, should be replaced by 'memset()' (due to length of patch file
I'm not going to list the diff -u here).
I am attaching the patch file(s) to this bug report...
