Replacing with a snprintf() and buffer overflow + handling. + +* a copy of Ip::Address::lookupHostIp to convert the input + string into IP address binary format, then generate the hex + string using the above new hex function instead of looped + sub-string concatenations across several buffers. + This removes all the "00" and "0000" strncat() calls and + allows far simpler code even with added buffer overflow + handling. + +* replace multiple string part concatenations with a few simpler + calls to snprintf() for all the search_ip buffer constructions. + Adding buffer overflow handling as needed for the new calls. +--- +Signed-off-by: Khem Raj <raj.khem@gmail.com> +Upstream-Status: Backport + + .../ext_edirectory_userip_acl.cc | 376 ++++++------------ + 1 file changed, 120 insertions(+), 256 deletions(-) + +diff --git a/helpers/external_acl/eDirectory_userip/ext_edirectory_userip_acl.cc b/helpers/external_acl/eDirectory_userip/ext_edirectory_userip_acl.cc +index 63609e4..ad16bfd 100644 +--- a/helpers/external_acl/eDirectory_userip/ext_edirectory_userip_acl.cc ++++ b/helpers/external_acl/eDirectory_userip/ext_edirectory_userip_acl.cc +@@ -67,6 +67,9 @@ + #ifdef HAVE_LDAP_H + #include <ldap.h> + #endif ++#ifdef HAVE_NETDB_H ++#include <netdb.h> ++#endif + + #ifdef HELPER_INPUT_BUFFER + #define EDUI_MAXLEN HELPER_INPUT_BUFFER +@@ -714,11 +717,14 @@ BindLDAP(edui_ldap_t *l, char *dn, char *pw, unsigned int t) + + /* Copy details - dn and pw CAN be NULL for anonymous and/or TLS */ + if (dn != NULL) { ++ if (strlen(dn) >= sizeof(l->dn)) ++ return LDAP_ERR_OOB;
