Summary
openjdk-8, openjdk-lts regressions
Details

USN-4607-1 fixed vulnerabilities and added features in OpenJDK. 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)
