Udgivelsen af forbindelsesbalanceren Odyssey 1.2","gt_translate_keys":[{"key":"rendered","format":"text"}]},"content":{"rendered":"

Korrigerende opdateringer er blevet udgivet for alle underst\u00f8ttede PostgreSQL-versioner: 14.1, 13.5, 12.9, 11.14, 10.19 og 9.6.24. Udgivelsen 9.6.24 vil v\u00e6re den sidste opdatering for 9.6-grenen, som nu er udg\u00e5et. Opdateringer for 10-grenen vil forts\u00e6tte indtil november 2022, 11 — indtil november 2023, 12 — indtil november 2024, 13 — indtil november 2025, 14 — indtil november 2026. <\/p>\n

De nye versioner omfatter mere end 40 rettelser og to s\u00e5rbarheder (CVE-2021-23214, CVE-2021-23222) i serverprocessen og klientbiblioteket libpq. S\u00e5rbarhederne tillader en angriber at tr\u00e6nge ind i den krypterede kommunikationskanal gennem en MITM-angreb. Angrebet kr\u00e6ver ikke en korrekt -certifikat og kan gennemf\u00f8res mod systemer, der kr\u00e6ver klientautentifikation via certifikat. SSL<\/a>I serverens kontekst muligg\u00f8r angrebet inds\u00e6ttelse af sin egen SQL-foresp\u00f8rgsel p\u00e5 tidspunktet for etablering af den krypterede forbindelse mellem klienten og PostgreSQL-serveren. I konteksten af libpq giver s\u00e5rbarheden angriberen mulighed for at returnere et falsk svar fra serveren til klienten. Kombinationen af s\u00e5rbarhederne kan tillade udtr\u00e6kning af oplysninger om adgangskoder eller andre fortrolige oplysninger fra klienten, der overf\u00f8res i begyndelsen af forbindelsen. <\/p>\n

Derudover kan det bem\u00e6rkes, at Yandex har offentliggjort en ny version af proxy-serveren Odyssey 1.2, der er designet til at opretholde en pulje af \u00e5bne forbindelser til PostgreSQL-databaser og organisere ruteplanl\u00e6gning af foresp\u00f8rgsler. Odyssey underst\u00f8tter k\u00f8rsel af flere arbejdsprocesser med multitr\u00e5dede behandlere, samt forbindelser til klienten. server<\/a> Der er mulighed for at binde forbindelsespuljer til brugere og databaser. Koden er skrevet i C og distribueres under BSD-licensen. <\/p>\n

I den nye version af Odyssey er der tilf\u00f8jet beskyttelse mod datainds\u00e6ttelse efter en SSL-session er etableret (muligg\u00f8r blokering af angreb ved hj\u00e6lp af de tidligere n\u00e6vnte s\u00e5rbarheder CVE-2021-23214 og CVE-2021-23222). Der er implementeret underst\u00f8ttelse af PAM og LDAP. Systemet kan nu integreres med overv\u00e5gningssystemet Prometheus. Beregningen af statistiske parametre for at tage h\u00f8jde for varigheden af transaktioner og foresp\u00f8rgsler er forbedret.
