Este disponibil un update corectiv pentru Firefox 97.0.2 \u0219i 91.6.1 care rezolv\u0103 dou\u0103 vulnerabilit\u0103\u021bi considerate critice. Aceste vulnerabilit\u0103\u021bi permit ocolirea izola\u021biei sandbox \u0219i permit executarea de cod cu privilegii de browser prin procesarea unui con\u021binut formatat special. Se afirm\u0103 c\u0103 pentru ambele probleme au fost identificate exploit-uri func\u021bionale care sunt deja utilizate pentru a efectua atacuri. <\/p>\n

Detaliile nu sunt \u00eenc\u0103 dezv\u0103luite, se \u0219tie doar c\u0103 prima vulnerabilitate (CVE-2022-26485) este legat\u0103 de accesarea unei zone de memorie deja eliberate (Use-after-free) \u00een codul de procesare a parametrului XSLT, iar a doua (CVE-2022-26486) implic\u0103 accesarea memoriei deja eliberate \u00een framework-ul IPC WebGPU. <\/p>\n

To\u021bi utilizatorii browserelor bazate pe motorul Firefox sunt ruga\u021bi s\u0103 instaleze urgent actualiz\u0103rile. Utilizatorii Tor Browser, bazat pe ramura ESR a Firefox 91, ar trebui s\u0103 fie deosebit de aten\u021bi la instalarea actualiz\u0103rilor, deoarece vulnerabilit\u0103\u021bile pot duce nu doar la compromiterea sistemului, ci \u0219i la de-anonimizarea utilizatorului. Update-ul care rezolv\u0103 aceste vulnerabilit\u0103\u021bi pentru Tor Browser nu a fost \u00eenc\u0103 preg\u0103tit.
