Ubuntu Security Notice USN-4607-1
October 27, 2020

openjdk-8, openjdk-lts vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.10
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in OpenJDK.

Software Description:
- openjdk-8: Open Source Java implementation
- openjdk-lts: Open Source Java implementation

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)
