Make sure destination can always hold the source data. memcpy(data,ptr+offset,length); data/g2clib-1.6.0/enc_jpeg2000.c:77:5: [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. char opts[MAXOPTSSIZE]; data/g2clib-1.6.0/enc_jpeg2000.c:97:8: [2] (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 string. strcat(opts,"\nnumgbits=4"); data/g2clib-1.6.0/enc_png.c:36:6: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(ptr+offset,data,length); data/g2clib-1.6.0/jpeg2000_openjpeg.c:55:3: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(buffer, &(mstream->pData[mstream->offset]), nb_bytes_read); data/g2clib-1.6.0/jpeg2000_openjpeg.c:70:3: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(&(mstream->pData[mstream->offset]), buffer, nb_bytes_write); data/g2clib-1.6.0/mainhome.c:53:14: [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. unsigned char mug[300],*cout; data/g2clib-1.6.0/pack_gp.c:40:12: [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. static char cfeed[1]; data/g2clib-1.6.0/reduce.c:35:12: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
