Unfortunately, that update introduced a regression that could cause TLS
connections with client certificate authentication to fail in some
situations. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

 It was discovered that OpenJDK incorrectly handled deserializing Proxy
 class objects with many interfaces. A remote attacker could possibly use
 this issue to cause a denial of service (memory consumption) via a
 specially crafted input. (CVE-2020-14779)

 Sergey Ostanin discovered that OpenJDK incorrectly restricted
 authentication mechanisms. A remote attacker could possibly use this
 issue to obtain sensitive information over an unencrypted connection.
 (CVE-2020-14781)

 It was discovered that OpenJDK incorrectly handled untrusted certificates.
 An attacker could possibly use this issue to read or write sensitive
 information. (CVE-2020-14782)

 Zhiqiang Zang discovered that OpenJDK incorrectly checked for integer
 overflows. An attacker could possibly use this issue to bypass certain
 Java sandbox restrictions. (CVE-2020-14792)

 Markus Loewe discovered that OpenJDK incorrectly checked permissions when
 converting a file system path to an URI. An attacker could possibly use
 this issue to bypass certain Java sandbox restrictions. (CVE-2020-14796)

 Markus Loewe discovered that OpenJDK incorrectly checked for invalid
 characters when converting an URI to a path. An attacker could possibly
 use this issue to read or write sensitive information. (CVE-2020-14797)

 Markus Loewe discovered that OpenJDK incorrectly checked the length of
 input strings. An attacker could possibly use this issue to bypass certain
 Java sandbox restrictions. (CVE-2020-14798)

 It was discovered that OpenJDK incorrectly handled boundary checks. An
 attacker could possibly use this issue to bypass certain Java sandbox
 restrictions. (CVE-2020-14803)");
