Unspecified vulnerability in Sun Java SE in JDK and JRE 5.0 before Update 22, JDK and JRE 6 before Update 17, SDK and JRE 1.3.x before 1.3.1_27, and SDK and JRE 1.4.x before 1.4.2_24 allows remote attackers to cause a denial of service (memory consumption) via crafted DER encoded data, which is not properly decoded by the ASN.1 DER input stream parser, aka Bug Id 6864911.

Security readout for executives and security teams

This older Sun Java vulnerability can let a remote attacker exhaust memory by sending specially crafted DER encoded data to affected Java runtimes. The known impact is denial of service, not data theft or code execution. Exposure is most likely in legacy systems still running affected Sun Java versions, especially applications that process externally supplied DER, ASN.1, or certificate-like data. Modern patched Java runtimes are not indicated as affected by the provided sources. Treat this as a legacy technology hygiene issue with service availability risk. It should be remediated when affected Java versions are found, but the provided sources do not support emergency prioritization based on active exploitation. Mitigation focus: Upgrade affected Java runtimes to the fixed versions or later named in vendor guidance.; Prioritize internet-facing or externally fed Java services that parse DER or ASN.1 data.; Retire unsupported Java 1.3.x, 1.4.x, 5.x, and early 6.x installations where possible..
