Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. ((char *)ret)[n] = '\0'; data/paraglob-0.5.0/src/ahocorasick/replace.c:295:9: [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( (AC_ALPHABET_t *) data/paraglob-0.5.0/src/ahocorasick/replace.c:437:13: [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 (&rd->noms[0], &rd->noms[index], data/paraglob-0.5.0/tools/benchmark.cpp:27:12: [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 buffer[1024]; data/paraglob-0.5.0/tools/benchmark.cpp:41:23: [2] (integer) atol: 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). long num_patterns = atol(a); data/paraglob-0.5.0/tools/benchmark.cpp:42:22: [2] (integer) atol: 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). long num_queries = atol(b); data/paraglob-0.5.0/tools/benchmark.cpp:43:21: [2] (integer) atol: Unless checked, the resulting number can exceed the expected range (CWE-190).

Consider using strcat_s, strncat, strlcat, or snprintf (warning: strncat is easily misused). Risk is low because the source is a constant character. strcat(buffer, "*"); ANALYSIS SUMMARY: Hits = 15 Lines analyzed = 3065 in approximately 0.16 seconds (19162 lines/second) Physical Source Lines of Code (SLOC) = 1680 Hits@level = [0] 14 [1] 3 [2] 9 [3] 0 [4] 3 [5] 0 Hits@level+ = [0+] 29 [1+] 15 [2+] 12 [3+] 3 [4+] 3 [5+] 0 Hits/KSLOC@level+ = [0+] 17.2619 [1+] 8.92857 [2+] 7.14286 [3+] 1.78571 [4+] 1.78571 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
