Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK 6 and 7, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to HotSpot. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from another vendor that this issue is related to incorrect MethodHandle lookups, which allows remote attackers to bypass Java sandbox restrictions.

Security readout for executives and security teams

CVE-2013-2421 is an old Java runtime issue in HotSpot. The sources say remote attackers could affect confidentiality, integrity, and availability, and another vendor linked it to Java sandbox bypass. Systems still running the affected Java or OpenJDK versions should be treated as legacy high-risk exposure. Exposure is most likely on endpoints, servers, or embedded applications retaining legacy Oracle Java SE 7 Update 17 or earlier, OpenJDK 6, or OpenJDK 7 packages from affected distributions. Prioritize remediation where legacy Java remains internet-facing, browser-accessible, or business-critical. This is not a new threat, but unpatched Java 6/7 is a durable risk indicator. Mitigation focus: Inventory all Oracle Java, OpenJDK, and IcedTea runtimes.; Apply applicable Oracle April 2013 CPU or distribution security updates.; Replace unsupported Java 6 or Java 7 deployments where possible..
