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/libapache2-mod-log-slow-1.0.8/mod_log_slow13.c Examining data/libapache2-mod-log-slow-1.0.8/mod_log_slow.c FINAL RESULTS: data/libapache2-mod-log-slow-1.0.8/mod_log_slow.c:53:5: [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 outbuf[LOGBUF_SIZE]; data/libapache2-mod-log-slow-1.0.8/mod_log_slow.c:88:11: [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). val = atol(arg); data/libapache2-mod-log-slow-1.0.8/mod_log_slow.c:155:5: [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 tstr[MAX_STRING_LEN]; data/libapache2-mod-log-slow-1.0.8/mod_log_slow.c:164:5: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
