Oracle Java t2k Type1 Subroutine Indexing Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the Oracle Java. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of Type1 fonts in t2k.dll. A file parsing vulnerability can occur by controlling a value placed after the “/Subrs” keyword in the eexec portion of the file which defines a size of an array. An attacker can leverage this to gain code execution under the context of the current user.
