Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, 6 Update 45 and earlier, and 5.0 Update 45 and earlier, and OpenJDK 7, allows remote attackers to affect confidentiality via unknown vectors related to Libraries, a different vulnerability than CVE-2013-2452 and CVE-2013-2455. NOTE: the previous information is from the June 2013 CPU. Oracle has not commented on claims from another vendor that this issue is due to an incorrect "checking order" within the AccessControlContext class.

Security readout for executives and security teams

CVE-2013-2443 is an old Java runtime vulnerability that could let a remote attacker compromise confidentiality on systems running affected Java SE or OpenJDK versions. The public record gives limited technical detail, so urgency depends on whether legacy Java 5, 6, 7, or OpenJDK 7 remains in use. Exposure is most likely in legacy Java runtime installations, older Linux Java packages, vendor-bundled runtimes, and systems that never completed the 2013 Java CPU update cycle. The bundle does not identify currently supported Java versions as affected. Treat this as a legacy exposure cleanup item unless affected Java runtimes are internet-facing or business-critical. The issue is old and sparsely described, but obsolete Java runtimes remain a common operational risk. Mitigation focus: Inventory Java SE 5, 6, 7 and OpenJDK 7 installations.; Apply Oracle June 2013 CPU or relevant vendor errata.; Retire unsupported legacy Java runtimes where possible..
