DSA-5672-1: openjdk-17 Security Advisory Updates

Recently, multiple vulnerabilities have been identified in the OpenJDK Java runtime which could lead to potential denial of service (DoS) or information disclosure scenarios. For those utilizing the oldstable distribution (bullseye), patches have been carefully deployed to mitigate these threats effectively.

Overview of Disclosed Vulnerabilities

  • CVE-2024-21011: This vulnerability is present in multiple Oracle products including Oracle Java SE and Oracle GraalVM. It primarily touches the Hotspot component, allowing unauthenticated attackers network access, leading to a partial DoS. Albeit challenging to exploit, the vulnerability demands attention from users handling API through web services.
  • CVE-2024-21012: Found within the Networking component of Oracle Java SE, this vulnerability could allow unauthenticated attackers access to update, insert, or delete certain accessible data. The risk is moderated by the inherent requirement for high-level access complexity to exploit.
  • CVE-2024-21068: Similar to CVE-2024-21011, this vulnerability impacts the Hotspot component and could allow unauthorized data manipulation. It is specifically critical for clients running sandboxed applications like Java Web Start or applets.
  • CVE-2024-21094: This vulnerability overlaps with the affected components and products of CVE-2024-21011, posing a similar threat regarding unauthorized data manipulation.
