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-cran-irace-3.4.1/src/iracebin/irace.c Examining data/r-cran-irace-3.4.1/src/iracebin/irace.h Examining data/r-cran-irace-3.4.1/src/iracebin/irace2pyimp.c FINAL RESULTS: data/r-cran-irace-3.4.1/src/iracebin/irace.h:76:12: [4] (shell) execvp: This causes a new program to execute and is difficult to use safely (CWE-78). try using a library call that implements the same functionality if available. return execvp(file, cmd_args); data/r-cran-irace-3.4.1/src/iracebin/irace.h:3:29: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. return (void *) ((char*)memcpy(dest, src, n) + n); data/r-cran-irace-3.4.1/src/iracebin/irace.h:23:24: [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). size_t len = strlen (s); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 98 in approximately 0.02 seconds (5026 lines/second) Physical Source Lines of Code (SLOC) = 75 Hits@level = [0] 0 [1] 1 [2] 1 [3] 0 [4] 1 [5] 0 Hits@level+ = [0+] 3 [1+] 3 [2+] 2 [3+] 1 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 40 [1+] 40 [2+] 26.6667 [3+] 13.3333 [4+] 13.3333 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
