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/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c FINAL RESULTS: data/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c:293:3: [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). strcpy(Netcdffile->name,filename); data/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c:325:3: [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). strcpy(Netcdf_att->name,attname); data/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c:1312:3: [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). strcpy(Netcdf_att->name,c_new_att_name); data/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c:1242:3: [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 c_dim_name[NC_MAX_NAME]; data/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c:1798:3: [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 c_var_name[NC_MAX_NAME]; data/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c:292:29: [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). Netcdffile->name=xmalloc((strlen(filename)+1)*sizeof(char)); data/ruby-netcdf-0.7.2/ext/numru/netcdfraw.c:324:29: [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).
