-- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the Oracle Java Runtime. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.
The specific flaw exists within the way java handles color profiles. When parsing a color profile containing a invalid 'ncl2' tag with an invalid value for DevCoords count it is possible to specify an integer that can cause an integer to wrap. This integer is then used to specify the size of a heap allocation. By providing a specially crafted tag value an attacker can cause memory corruption that can lead to remote code being executed under to user running the browser.
