The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that OpenJDK incorrectly handled certain regular expressions. An attacker could possibly use this issue to cause a denial of service while processing a specially crafted regular expression. (CVE-2020-2754, CVE-2020-2755)

It was discovered that OpenJDK incorrectly handled class descriptors and catching exceptions during object stream deserialization. An attacker could possibly use this issue to cause a denial of service while processing a specially crafted serialized input. (CVE-2020-2756, CVE-2020-2757)

Bengt Jonsson, Juraj Somorovsky, Kostis Sagonas, Paul Fiterau Brostean and Robert Merget discovered that OpenJDK incorrectly handled certificate messages during TLS handshake.

(CVE-2020-2767)

It was discovered that OpenJDK incorrectly handled exceptions thrown by unmarshalKeyInfo() and unmarshalXMLSignature(). An attacker could possibly use this issue to cause a denial of service while reading key info or XML signature data from XML input. (CVE-2020-2773)

Peter Dettman discovered that OpenJDK incorrectly handled SSLParameters in setAlgorithmConstraints(). An attacker could possibly use this issue to override the defined systems security policy and lead to the use of weak crypto algorithms that should be disabled.
This issue only affected OpenJDK 11. (CVE-2020-2778)

Simone Bordet discovered that OpenJDK incorrectly re-used single null TLS sessions for new TLS connections. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2020-2781)
