Prezentate<\/a><\/noindex> versiuni corective ale instrumentului Tor (0.3.5.11, 0.4.2.8, 0.4.3.6 \u0219i 4.4.2-alpha), utilizat pentru organizarea re\u021belei anonime Tor. \u00cen noile versiuni, a fost eliminat\u0103 vulnerabilitatea<\/a><\/noindex> (CVE-2020-15572), cauzat\u0103 de accesarea unei zone de memorie \u00een afara limitelor buffer-ului alocat. Vulnerabilitatea permite unui atacator de la distan\u021b\u0103 s\u0103 ini\u021bieze o pr\u0103bu\u0219ire a procesului tor. Problema se manifest\u0103 doar \u00een cazul construirii cu biblioteca NSS (\u00een mod implicit, Tor este construit cu OpenSSL, iar utilizarea NSS necesit\u0103 specificarea flag-ului «—enable-nss»).<\/p>\n

\u00cen plus la sf\u00e2r\u0219itul anului 2019. Pe l\u00e2ng\u0103 protocoalele ActivityPub \u0219i diaspora, Hubzilla se federeaz\u0103 \u00een cadrul re\u021belei prin propriul s\u0103u protocol<\/a><\/noindex> planul de \u00eencetare a suportului pentru a doua versiune a protocolului pentru serviciile onion (anterior cunoscut sub denumirea de servicii ascunse). Cu un an \u0219i jum\u0103tate \u00een urm\u0103, \u00een versiunea 0.3.2.9, utilizatorii au fost propus\u0103<\/a><\/noindex> a treia versiune a protocolului pentru serviciile onion, notabil\u0103 prin trecerea la adrese de 56 de caractere, o protec\u021bie mai fiabil\u0103 \u00eempotriva scurgerilor de date prin serverele de director, o structur\u0103 modular\u0103 extins\u0103 \u0219i utilizarea algoritmilor SHA3, ed25519 \u0219i curve25519 \u00een loc de SHA1, DH \u0219i RSA-1024. <\/p>\n

A doua versiune a protocolului a fost dezvoltat\u0103 acum aproximativ 15 ani \u0219i din cauza utiliz\u0103rii algoritmilor \u00eenvechi\u021bi, \u00een condi\u021biile de ast\u0103zi, nu mai poate fi considerat\u0103 sigur\u0103. Av\u00e2nd \u00een vedere expirarea timpului de suport pentru versiunile vechi, orice gateway Tor actual sus\u021bine a treia versiune a protocolului, care este oferit\u0103 implicit la crearea de noi servicii onion. <\/p>\n

Pe 15 septembrie 2020, Tor va \u00eencepe s\u0103 avertizeze operatorii \u0219i clien\u021bii cu privire la expirarea celei de-a doua versiuni a protocolului. Pe 15 iulie 2021, suportul pentru a doua versiune a protocolului va fi eliminat din baza de cod, iar pe 15 octombrie 2021 va fi lansat\u0103 o nou\u0103 versiune stabil\u0103 a Tor f\u0103r\u0103 suport pentru vechiul protocol. Astfel, de\u021bin\u0103torii de servicii onion vechi au 16 luni pentru a trece la noua versiune a protocolului, care necesit\u0103 generarea unui nou adres\u0103 de 56 de caractere pentru serviciu.<\/p>\n
