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)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
