(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused). Risk is low because the source is a constant string.
strcpy(Size, "MediaSize=iso_a4_210x297mm;");

data/c2esp-27/src/c2espcommon.h:38:8: [2] (buffer) char:
Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the
maximum possible length.
extern char BackBuf[32000]; //for the back channel replies from the printer

char line[1024], /* Line from file */
data/c2esp-27/src/command2esp.c:142:15: [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 ((fp = fopen(argv[6], "r")) == NULL)
data/c2esp-27/src/c2espC.c:682:8: [1] (buffer) fgetc:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
c=fgetc(CompData);
data/c2esp-27/src/c2espcommon.c:70:5: [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(ExtLogFileName)>0)
data/c2esp-27/src/c2espcommon.c:98:2: [1] (buffer) strncat:
Easily used incorrectly (e.g., incorrectly computing the correct maximum
size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings.
strncat(CupsFormat,PrintFormat,150); //crop PrintFormat to avoid FAILING WITH BUFFER OVERFLOW
data/c2esp-27/src/c2espcommon.c:100:16: [1] (buffer) strlen:

perform an over-read (it could cause a crash if unprotected) (CWE-126).

data/c2esp-27/src/c2espcommon.c:100:45: [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.
