FINAL RESULTS:
data/astropy-healpix-0.5/cextern/astrometry.net/CuTest.c:24:2: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).
strcpy(newStr, old);
data/astropy-healpix-0.5/cextern/astrometry.net/CuTest.c:75:2: [4] (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).
strcat(str->buffer, text);
data/astropy-healpix-0.5/cextern/astrometry.net/CuTest.c:91:2: [4] (format) vsprintf:
Potential format string problem (CWE-134). Make format string constant.
vsprintf(buf, format, argp);
data/astropy-healpix-0.5/cextern/astrometry.net/CuTest.c:152:2: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(buf, "%s:%d: ", file, line);
data/astropy-healpix-0.5/cextern/astrometry.net/bl-nl.h:53:28: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.
InlineDeclare number* NLF(access)(nl* list, size_t n);
data/astropy-healpix-0.5/cextern/astrometry.net/bl.h:221:15: [4] (format) printf:

(CWE-134). Use a constant for the format specification.
ATTRIB_FORMAT(printf,2,3)
data/astropy-healpix-0.5/cextern/astrometry.net/bl.h:279:15: [4] (format) printf:

ATTRIB_FORMAT(printf,2,3)
data/astropy-healpix-0.5/cextern/astrometry.net/bl.h:289:15: [4] (format) printf:
