Description Tomas Hoger 2020-10-19 09:10:59 UTC 
It was discovered that the Hotspot component of OpenJDK did not properly check for integer overflows when when optimizing code, leading to out-of-bounds access.  An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions.
