Description Tomas Hoger 2018-10-24 07:55:16 UTC

A flaw was found in the Utility component of OpenJDK.  The Multi-Release attribute could have been read from outside of the main attributes in a Jar manifest, possibly leading to a use of an unsigned value for this attribute.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
