Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/asterisk-espeak-5.0~1/app_espeak.c FINAL RESULTS: data/asterisk-espeak-5.0~1/app_espeak.c:171:12: [2] (misc) fopen: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents? (CWE-362). if ((fl = fopen(fname, "r")) == NULL) { data/asterisk-espeak-5.0~1/app_espeak.c:222:12: [2] (misc) fopen: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents?

Some older Unix-like systems create temp files with permission to write by all by default, so be sure to set the umask to override this. Also, some older Unix systems might fail to use O_EXCL when opening the file, so make sure that O_EXCL is used by the library (CWE-377). if ((raw_fd = mkstemp(raw_name)) == -1) { data/asterisk-espeak-5.0~1/app_espeak.c:291:7: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). if (strlen(cachedir) + strlen(MD5_name) + 6 <= MAXLEN) { data/asterisk-espeak-5.0~1/app_espeak.c:291:26: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). if (strlen(cachedir) + strlen(MD5_name) + 6 <= MAXLEN) { data/asterisk-espeak-5.0~1/app_espeak.c:350:39: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). espk_error = espeak_Synth(args.text, strlen(args.text), 0, POS_CHARACTER, data/asterisk-espeak-5.0~1/app_espeak.c:351:10: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126).
