Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE JDK and JRE, 7, 6 Update 27 and earlier, and 5.0 Update 31 and earlier allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability via unknown vectors related to Deserialization.

Security readout for executives and security teams

This is an old Oracle Java vulnerability affecting Java SE JDK/JRE versions 7, 6 Update 27 and earlier, and 5.0 Update 31 and earlier. A malicious untrusted Java applet or Java Web Start application could compromise confidentiality, integrity, and availability. Business risk is mainly legacy systems that still allow Java browser or Web Start execution. Exposure is most likely on legacy endpoints, servers, or bundled applications running Oracle Java SE JDK/JRE 7, 6u27 or earlier, or 5.0u31 or earlier, especially where Java applets or Web Start can launch untrusted content. Treat this as a legacy Java cleanup and exposure-reduction item. It is high impact if vulnerable Java can execute untrusted applets or Web Start content, but urgency depends on whether such legacy runtimes remain in use. Mitigation focus: Identify all Oracle Java JDK/JRE installations at or below the affected versions.; Apply the relevant Oracle Java CPU or OS vendor security update.; Remove or disable Java browser plugin and Web Start where not required..
