Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/libpam-net-0.3/pam_net_checkgroup.c Examining data/libpam-net-0.3/pam_net_checkgroup.h Examining data/libpam-net-0.3/pam_newnet.c Examining data/libpam-net-0.3/pam_usernet.c FINAL RESULTS: data/libpam-net-0.3/pam_usernet.c:101:2: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
