Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/libgusb-0.3.5/gusb/gusb-autocleanups.h Examining data/libgusb-0.3.5/gusb/gusb-context-private.h Examining data/libgusb-0.3.5/gusb/gusb-context.c Examining data/libgusb-0.3.5/gusb/gusb-context.h Examining data/libgusb-0.3.5/gusb/gusb-device-list.c Examining data/libgusb-0.3.5/gusb/gusb-device-list.h Examining data/libgusb-0.3.5/gusb/gusb-device-private.h Examining data/libgusb-0.3.5/gusb/gusb-device.c Examining data/libgusb-0.3.5/gusb/gusb-device.h Examining data/libgusb-0.3.5/gusb/gusb-endpoint-private.h Examining data/libgusb-0.3.5/gusb/gusb-endpoint.c Examining data/libgusb-0.3.5/gusb/gusb-endpoint.h Examining data/libgusb-0.3.5/gusb/gusb-interface-private.h Examining data/libgusb-0.3.5/gusb/gusb-interface.c Examining data/libgusb-0.3.5/gusb/gusb-interface.h Examining data/libgusb-0.3.5/gusb/gusb-private.h Examining data/libgusb-0.3.5/gusb/gusb-self-test.c Examining data/libgusb-0.3.5/gusb/gusb-source.c Examining data/libgusb-0.3.5/gusb/gusb-source.h Examining data/libgusb-0.3.5/gusb/gusb-util.c Examining data/libgusb-0.3.5/gusb/gusb-util.h Examining data/libgusb-0.3.5/gusb/gusb-version.c Examining data/libgusb-0.3.5/gusb/gusb.h Examining data/libgusb-0.3.5/tools/gusb-main.c FINAL RESULTS: data/libgusb-0.3.5/gusb/gusb-device.c:872:11: [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. unsigned char buf[128]; data/libgusb-0.3.5/gusb/gusb-endpoint.c:70:2: [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 (&endpoint->endpoint_descriptor, data/libgusb-0.3.5/gusb/gusb-interface.c:77:2: [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 (&interface->iface, data/libgusb-0.3.5/tools/gusb-main.c:119:9: [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). len = strlen (item->name); ANALYSIS SUMMARY: Hits = 4 Lines analyzed = 5656 in approximately 0.20 seconds (28261 lines/second) Physical Source Lines of Code (SLOC) = 3453 Hits@level = [0] 0 [1] 1 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 4 [1+] 4 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 1.15841 [1+] 1.15841 [2+] 0.86881 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
