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/xwrited-3/xwd-application.c Examining data/xwrited-3/xwd-application.h Examining data/xwrited-3/xwd-utmp-utempter.c Examining data/xwrited-3/xwd-utmp-utmpx.c Examining data/xwrited-3/xwd-utmp.h Examining data/xwrited-3/xwrited.c FINAL RESULTS: data/xwrited-3/xwd-application.c:110:4: [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(oct, p + 1, 3); data/xwrited-3/xwd-application.c:449:18: [2] (misc) open: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents? (CWE-362). self->slavefd = open(slave_name, O_RDWR); data/xwrited-3/xwd-utmp-utmpx.c:52:11: [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). line += strlen(DEV_PREFIX); data/xwrited-3/xwd-utmp-utmpx.c:55:13: [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). line_len = strlen(line); data/xwrited-3/xwd-utmp-utmpx.c:67:2: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy(utmpx.ut_name, pwd->pw_name, sizeof (utmpx.ut_name)); data/xwrited-3/xwd-utmp-utmpx.c:68:2: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy(utmpx.ut_id, id, sizeof (utmpx.ut_id)); data/xwrited-3/xwd-utmp-utmpx.c:69:2: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). strncpy(utmpx.ut_line, line, sizeof (utmpx.ut_line)); ANALYSIS SUMMARY: Hits = 7 Lines analyzed = 898 in approximately 0.04 seconds (21391 lines/second) Physical Source Lines of Code (SLOC) = 561 Hits@level = [0] 0 [1] 5 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 7 [1+] 7 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 12.4777 [1+] 12.4777 [2+] 3.56506 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
