Red Hat Product Errata RHSA-2014:1636 0 normal SHIPPED_LIVE Important: java-1.8.0-openjdk security update 2014-10-15 07:03:25 UTC

Description Tomas Hoger 2014-10-13 09:20:12 UTC
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 20:14:40 UTC
Public now via Oracle Critical Patch Update - October 2014.  Fixed in Oracle Java SE 8u25.
