Tackling various vulnerabilities within OpenJDK 8 on Ubuntu, fortifying defenses against external threats and guaranteeing secure functionalities.
Several security issues were fixed in OpenJDK 8.

Summary

Several security issues were fixed in OpenJDK 8.

Software Description:

- openjdk-8: Open Source Java implementation

Details:

Karthik Bhargavan and Gaetan Leurent discovered that the DES and

Triple DES ciphers were vulnerable to birthday attacks. A remote

attacker could possibly use this flaw to obtain clear text data from

long encrypted sessions. This update moves those algorithms to the

legacy algorithm set and causes them to be used only if no non-legacy

algorithms can be negotiated. (CVE-2016-2183)

It was discovered that OpenJDK accepted ECSDA signatures using

non-canonical DER encoding. An attacker could use this to modify or

expose sensitive data. (CVE-2016-5546)

It was discovered that OpenJDK did not properly verify object

identifier (OID) length when reading Distinguished Encoding Rules

(DER) records, as used in x.509 certificates and elsewhere. An

attacker could use this to cause a denial of service (memory

consumption). (CVE-2016-5547)

It was discovered that covert t...
