Au fost publicate actualiz\u0103ri corective pentru sistemul distribuit de gestionare a codului surs\u0103 Git 2.30.2, 2.17.6, 2.18.5, 2.19.6, 2.20.5, 2.21.4, 2.22.5, 2.23.4, 2.24.4, 2.25.5, 2.26.3, 2.27.1, 2.28.1 \u0219i 2.29.3, \u00een care a fost remediat\u0103 o vulnerabilitate (CVE-2021-21300), care permite executarea de cod de la distan\u021b\u0103 atunci c\u00e2nd se cloneaz\u0103 un repository al unui atacator folosind comanda «git clone». Toate versiunile Git, \u00eencep\u00e2nd cu versiunea 2.15, sunt afectate de aceste vulnerabilit\u0103\u021bi. <\/p>\n

Problema se manifest\u0103 atunci c\u00e2nd se folosesc opera\u021bii am\u00e2nate de checkout, utilizate \u00een anumite filtre de cur\u0103\u021bare, cum ar fi cele configurate \u00een Git LFS. Exploatarea vulnerabilit\u0103\u021bii este posibil\u0103 doar pe sisteme de fi\u0219iere care nu fac distinc\u021bie \u00eentre majuscule \u0219i minuscule, dar care suport\u0103 linkuri simbolice, precum NTFS, HFS+ \u0219i APFS (adic\u0103 pe platformele Windows \u0219i macOS). <\/p>\n

Ca solu\u021bie temporar\u0103 pentru protec\u021bie, se poate dezactiva \u00een git procesarea leg\u0103turilor simbolice, execut\u00e2nd «git config —global core.symlinks false», sau se poate dezactiva suportul pentru procesele-filtru folosind comanda «git config —show-scope —get-regexp ‘filter\..*\.process'». De asemenea, se recomand\u0103 evitarea clon\u0103rii repository-urilor necertificate.
