OpenSSL kr\u00fcptograafilises raamatukogus on leitud haavatavus (CVE ei ole veel m\u00e4\u00e4ratud), mille abil saab kaugt\u00e4iendaja kahjustada protsessi m\u00e4lu sisu, saates spetsiaalselt vormistatud andmeid TLS-\u00fchenduse loomise ajal. Praegu pole selge, kas probleem v\u00f5ib viia r\u00fcndaja koodi t\u00e4itmiseni ja andmete lekkimiseni protsessi m\u00e4lust v\u00f5i on see piiratud ainult \u00f5nnetuga. <\/p>\n

Haavatavus ilmneb OpenSSL 3.0.4 v\u00e4ljalaskes, mis anti v\u00e4lja 21. juunil, ja see on p\u00f5hjustatud vigasest vigade parandamisest koodis, mille t\u00f5ttu v\u00f5ib kirjutada v\u00f5i lugeda kuni 8192 baiti andmeid eraldatud puhvrisse. Haavatavuse \u00e4rakasutamine on v\u00f5imalik ainult x86_64 s\u00fcsteemides, millel on AVX512 instruktsioonide tugi. <\/p>\n

Sellised OpenSSL-i k\u00f5rvalharud nagu BoringSSL ja LibreSSL, samuti OpenSSL 1.1.1 haru ei ole probleemile vastuv\u00f5tlikud. Parandus on praegu saadaval ainult plaastrina. Halvimal juhul v\u00f5ib probleem osutuda ohtlikumaks kui Heartbleed haavatavus, kuid ohutaset alandab see, et haavatavus ilmneb ainult OpenSSL 3.0.4 versioonis, samas kui paljud jaotused j\u00e4tkavad vaikimisi 1.1.1 haru tarnimist v\u00f5i ei ole veel j\u00f5udnud pakettide uuendusi versiooniga 3.0.4 koostada.
