USN-4607-2: OpenJDK regressions
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)
