Size of
record_nameisMAXLEN_PATH(1024) + 1butfile_pathmay have data uptoMAXLEN_CFG_LINE(MAXLEN_PATH*4) + 1. So a check was missing inzlog_rule_new()while copying therecord_namefromfile_path + 1which caused the buffer overflow. An attacker can exploit this vulnerability to overwrite thezlog_record_fn record_funcfunction pointer to get arbitrary code execution.
