Arch Linux Security Advisory ASA-202107-53 ========================================== Severity: High Date : 2021-07-21 CVE-ID : CVE-2021-2341 CVE-2021-2369 CVE-2021-2388 Package : jdk11-openjdk Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-2189 Summary ======= The package jdk11-openjdk before version 11.0.12.u7-1 is vulnerable to multiple issues including arbitrary code execution and information disclosure. Resolution ========== Upgrade to 11.0.12.u7-1. # pacman -Syu "jdk11-openjdk>=11.0.12.u7-1" The problems have been fixed upstream in version 11.0.12.u7. Workaround ========== None. Description =========== - CVE-2021-2341 (information disclosure) A security issue has been found in the Networking component of OpenJDK versions 7u301, 8u291, 11.0.11 and 16.0.1. A difficult to exploit vulnerability allows an unauthenticated attacker with network access via multiple protocols to compromise OpenJDK. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of OpenJDK accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). - CVE-2021-2369 (arbitrary code execution) A security issue has been found in the Library component of OpenJDK versions 7u301, 8u291, 11.0.11 and 16.0.1. An easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise OpenJDK. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of the OpenJDK accessible data. Note : This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). - CVE-2021-2388 (arbitrary code execution) A security issue has been found in the Hotspot component of OpenJDK versions 7u301, 8u291, 11.0.11 and 16.0.1. A difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise OpenJDK. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of OpenJDK. Note : This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). Impact ====== A malicious Java application could bypass security restrictions to run arbitrary code or disclose sensitive information.
