Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/r-bioc-multtest-2.46.0/src/Rpack.c Examining data/r-bioc-multtest-2.46.0/src/VScount.c Examining data/r-bioc-multtest-2.46.0/src/block_sampling_fixed.c Examining data/r-bioc-multtest-2.46.0/src/bootloop.c Examining data/r-bioc-multtest-2.46.0/src/mt.c Examining data/r-bioc-multtest-2.46.0/src/mt.h Examining data/r-bioc-multtest-2.46.0/src/pairt_sampling.c Examining data/r-bioc-multtest-2.46.0/src/pairt_sampling_fixed.c Examining data/r-bioc-multtest-2.46.0/src/random.c Examining data/r-bioc-multtest-2.46.0/src/sampling.c Examining data/r-bioc-multtest-2.46.0/src/sampling_fixed.c Examining data/r-bioc-multtest-2.46.0/src/stat_func.c Examining data/r-bioc-multtest-2.46.0/src/stat_order.c FINAL RESULTS: data/r-bioc-multtest-2.46.0/src/mt.h:11:9: [4] (format) fprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. #define fprintf win_print data/r-bioc-multtest-2.46.0/src/stat_func.c:703:3: [4] (buffer) fscanf: The scanf() family's %s operation, without a limit specification, permits buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a different input function. fscanf(fh, "%s", pdata->name); data/r-bioc-multtest-2.46.0/src/stat_func.c:710:5: [4] (buffer) fscanf: The scanf() family's %s operation, without a limit specification, permits buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a different input function. fscanf(fh, "%s", pdata->id[i]); data/r-bioc-multtest-2.46.0/src/Rpack.c:58:18: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. if(PrintIDX) sprintf(pdata->id[i],"%d",i+1); /*used for the indexes*/ data/r-bioc-multtest-2.46.0/src/Rpack.c:81:16: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190). If source untrusted, check both minimum and maximum, even if the input had no minus sign (large numbers can roll over into negative number; consider saving to an unsigned value if that is intended). indexes[i]=atoi(pdata->id[i]); data/r-bioc-multtest-2.46.0/src/block_sampling_fixed.c:57:5: [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(L,l_L,sizeof(int)*l_n); data/r-bioc-multtest-2.46.0/src/mt.h:53:3: [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 name[MAX_ID];/*the name of the status*/ data/r-bioc-multtest-2.46.0/src/pairt_sampling_fixed.c:21:3: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120).
