Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability exists within the Java Runtime Environment (JRE) component of Oracle Java SE. This flaw is related to the Concurrency subcomponent. This weakness allows remote attackers to affect the confidentiality, integrity, and availability of systems. The impact could include unauthorized operating system takeover and arbitrary code execution.
- Vulnerable: Java Runtime Environment (JRE)
- Flaw: Type confusion in array operations
- Impact: System takeover, code execution
Attack Path
How an attacker could exploit the issue
This vulnerability in the Java Runtime Environment could allow remote attackers to compromise systems. Attackers can leverage this by presenting specially crafted content that exploits a flaw in how the Java Runtime Environment handles certain concurrent operations. This could lead to a denial of service by crashing the Java Virtual Machine or bypassing security restrictions, potentially impacting the confidentiality, integrity, and availability of affected systems.
- Exposure via network
- Attacker sends crafted content
- Result: system crash or sandbox bypass
