PostgreSQL 9.4.2, 9.3.7, 9.2.11, 9.1.16 和 9.0.20 发布,这些版本现已提供 下载。此版本修复了 PostgreSQL 9.3 和 9.4 版本中的数据崩溃问题,强烈建议用户尽快升级到最新版本!
安全修复
-
CVE-2015-3165 Double “free” after authentication timeout.
-
CVE-2015-3166 Unanticipated errors from the standard library.
-
CVE-2015-3167 pgcrypto has multiple error messages for decryption with an incorrect key.
此外,我们建议所有用户使用 Kerberos、 GSSAPI 或 SSPI 身份验证设置 pg_hba.conf 中的 include_realm 为 1,未来版本中都将默认这个设置。
新版本中相比老版本中有个不同的返回类型,所以在升级之前 CIText 用户需要先运行”ALTER EXTENSION citext UPDATE”功能测试应用程序。
