Dup\u0103 trei ani de dezvoltare, a fost publicat\u0103 versiunea 1.7 a utilitarului GNU cflow, destinat construirii unui grafic vizual al apelurilor de func\u021bii \u00een programele scrise \u00een C, care poate fi folosit pentru a facilita \u00een\u021belegerea logicii unei aplica\u021bii. Graficul este construit exclusiv pe baza analizei codului surs\u0103, f\u0103r\u0103 a necesita executarea programului. Se suport\u0103 generarea at\u00e2t a grafurilor directe, c\u00e2t \u0219i a celor inverse ale fluxurilor de execu\u021bie, precum \u0219i generarea listelor de referin\u021be \u00eencruci\u0219ate pentru fi\u0219ierele cu cod. <\/p>\n

Versiunea se remarc\u0103 prin implementarea suportului pentru formatul de ie\u0219ire \"dot\" (\"--format=dot\") pentru generarea de rezultate \u00een limbajul DOT pentru vizualizare ulterioar\u0103 \u00een pachetul Graphviz. A fost ad\u0103ugat\u0103 posibilitatea de a specifica mai multe func\u021bii de start prin duplicarea op\u021biunilor \"--main\"; pentru fiecare dintre aceste func\u021bii va fi generat un grafic separat. De asemenea, a fost introdus\u0103 op\u021biunea \"--target=FUNCTION\" care permite limitarea graficului rezultat doar la ramura ce include func\u021bii specifice (op\u021biunea \"--target\" poate fi specificat\u0103 de mai multe ori). \u00cen modul cflow, au fost ad\u0103ugate comenzi noi pentru navigarea prin grafic: \"c\" \u2014 trecere la func\u021bia apelant\u0103, \"n\" \u2014 trecere la urm\u0103toarea func\u021bie de la acest nivel de imbricare \u0219i \"p\" \u2014 trecere la func\u021bia anterioar\u0103 cu acela\u0219i nivel de imbricare. <\/p>\n

\u00cen noua versiune au fost, de asemenea, eliminate dou\u0103 vulnerabilit\u0103\u021bi care au fost descoperite \u00eenc\u0103 din 2019 \u0219i care duc la coruperea memoriei atunci c\u00e2nd se prelucreaz\u0103 \u00een cflow coduri surs\u0103 special concepute. Prima vulnerabilitate (CVE-2019-16165) este cauzat\u0103 de accesarea memoriei dup\u0103 ce aceasta a fost eliberat\u0103 (use-after-free) \u00een codul parserului (func\u021bia reference din parser.c). A doua vulnerabilitate (CVE-2019-16166) este legat\u0103 de dep\u0103\u0219irea buffer-ului \u00een func\u021bia nexttoken(). Potrivit dezvoltatorilor, problemele men\u021bionate nu prezint\u0103 o amenin\u021bare pentru securitate, deoarece se limiteaz\u0103 la \u00eenchiderea nea\u0219teptat\u0103 a utilitarului.
