Git'is avastav kriitiline haavatavus (CVE-2021-29468), mis ilmneb ainult Cygwini keskkonna jaoks kogumisel (teek, mis simuleerib p\u00f5hilise Linuxi API-d Windowsis ja komplekti t\u00fc\u00fcpilisi Linuxi programme Windowsile). Haavatavus v\u00f5imaldab r\u00fcndajal t\u00e4ita koodi andmete hankimisel (\"git checkout\") r\u00fcndaja kontrolli all olevast repositooriumist. Probleem on lahendatud Cygwini jaoks git pakendis 2.31.1-2. Peamiselt Git'i projektis pole probleem praegu lahendatud (on ebat\u00f5en\u00e4oline, et keegi kogub git'i Cygwini jaoks k\u00e4sitsi, mitte ei kasuta valmispaketti). <\/p>\n

Haavatavus tuleneb Cygwini keskkonna k\u00e4sitlemisest Unixitaolisena, mitte Windowsina, mis toob kaasa piirangute puudumise tagasihoidlikule s\u00fcmbolile ‘\’ teel, samas kui Cygwinis, nagu ka Windowsis, v\u00f5ib seda s\u00fcmbolit kasutada kataloogide eraldamiseks. L\u00f5pptulemusena, spetsiaalselt muudetud repositooriumi loomise kaudu, mis sisaldab s\u00fcmboolseid linke ja faile tagasihoidlikku s\u00fcmbolit, on v\u00f5imalik saavutada suvaliste failide \u00fclekirjutamine, kui see repositoorium Cygwini laaditakse (Windowsi jaoks m\u00f5eldud Git'is lahendati sarnane haavatavus 2019. aastal). Failide \u00fclekirjutamise v\u00f5imaluse saavutamisel saab r\u00fcndaja \u00fcle kirjutada git'i hook-kutsed ja saavutada suvalise koodi t\u00e4itmine s\u00fcsteemis.
