Autorul framework-ului web scris \u00een limbajul Rust actix-web<\/a><\/noindex> a \u0219ters repository<\/a><\/noindex> dup\u0103 ce a fost aspru criticat pentru «utilizarea incorect\u0103» a limbajului Rust. Framework-ul actix-web, pachetul cu care a fost desc\u0103rcat de peste 800 de mii de ori, permite integrarea func\u021bionalit\u0103\u021bii unui server \u0219i client HTTP \u00een aplica\u021biile scrise \u00een Rust, fiind concentrat pe atingerea performan\u021bei maxime. lider<\/a><\/noindex> \u00een multe teste de framework-uri web.<\/p>\n

Cu pu\u021bin timp \u00eenainte de incident, \u00een issues pe GitHub a fost raportat\u0103 o comportare nedefinit\u0103 (Undefined Behaviour) \u00een codul serverului actix-web, ap\u0103rut\u0103 \u00eentr-un bloc executat \u00een modul unsafe<\/a><\/noindex> (care permite efectuarea de ac\u021biuni nesigure cu pointere). Autorul actix-web nu a \u00eendep\u0103rtat blocul unsafe, dar a ref\u0103cut apelul acestui bloc pentru a evita apari\u021bia comport\u0103rii nedefinite. Propunerile de a elimina unsafe au fost respinse de autor, care a invocat pierderea posibil\u0103 de performan\u021b\u0103 \u0219i a afirmat c\u0103 nu folose\u0219te unsafe f\u0103r\u0103 necesitate \u0219i este \u00eencrez\u0103tor \u00een siguran\u021ba blocurilor care func\u021bioneaz\u0103 \u00een acest mod.<\/p>\n

Un membru al echipei RustSec, care a descoperit comportarea nedefinit\u0103, nu a fost de acord \u0219i a sugerat c\u0103 utilizarea multor blocuri unsafe \u00een actix-web este injustificat\u0103. Dup\u0103 aceasta, el a publicat
\narticol<\/a><\/noindex> un articol despre inacceptabilitatea utiliz\u0103rii unsafe, \u00een care, printre altele, s-a men\u021bionat c\u0103 tehnica folosit\u0103 \u00een actix-web pentru manipularea pointerelor (mai multe pointere mutable c\u0103tre acelea\u0219i date) poate duce la vulnerabilit\u0103\u021bi de tip use-after-free \u0219i nu respect\u0103 paradigma de dezvoltare \u00een Rust. <\/p>\n
