Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). strcpy(ret, s1); data/lua-cyrussasl-1.1.0/context.c:163:3: [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(ctx->user, usr, ulen); data/lua-cyrussasl-1.1.0/cyrussasl.c:134:5: [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(out_user, str, len + 1); data/lua-cyrussasl-1.1.0/cyrussasl.c:1144:5: [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 err[256]; data/lua-cyrussasl-1.1.0/cyrussasl.c:1183:5: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
