Description Tomas Hoger 2014-10-13 05:20:12 EDT

It was discovered that the Libraries component in OpenJDK failed to properly handle ZIP archives that contain entries with NUL byte ('\0') used in the file name.  When extracting data from such archives, OpenJDK could use different file than expected.  An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

Comment 1 Tomas Hoger 2014-10-14 16:14:40 EDT

Public now via Oracle Critical Patch Update - October 2014.  Fixed in Oracle Java SE 8u25.
