data/biometric-authentication-0.9.70/src/lib/biometric_storage.c:858:11: [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).

data/biometric-authentication-0.9.70/src/lib/biometric_storage.c:861:4: [1] (buffer) strncpy:
Easily used incorrectly; doesn't always \0-terminate or check for invalid
pointers [MS-banned] (CWE-120).

data/biometric-authentication-0.9.70/src/lib/biometric_storage.c:877:3: [1] (buffer) strcat:
Does not check for buffer overflows when concatenating to destination
[MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
snprintf (warning: strncat is easily misused). Risk is low because the
source is a constant character.

Does not handle strings that are not \0-terminated; if given one it may

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).
