If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
ret = vfprintf(stderr, fmt, va);
data/libcapi20-3-3.27/capi20.c:312:3: [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).

data/libcapi20-3-3.27/capi20.c:314:3: [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).

data/libcapi20-3-3.27/convert.c:851:8: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,

a constant for the format specification.

be set more than once (CWE-807, CWE-20). Check environment variables
carefully before using them.
