Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/r-cran-irlba-2.3.3/src/irlb.h Examining data/r-cran-irlba-2.3.3/src/utility.c Examining data/r-cran-irlba-2.3.3/src/irlb.c FINAL RESULTS: data/r-cran-irlba-2.3.3/src/irlb.c:45:3: [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 buf[4096]; data/r-cran-irlba-2.3.3/src/irlb.c:143:7: [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 (scale, REAL (SCALE), n * sizeof (double)); data/r-cran-irlba-2.3.3/src/irlb.c:167:7: [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 (REAL (V), REAL (RV), n * (restart + 1) * sizeof (double)); data/r-cran-irlba-2.3.3/src/irlb.c:168:7: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120).
