Unspecified vulnerability in the 2D component in Oracle Java SE and Java for Business 6 Update 21, 5.0 Update 25, and 1.4.2_27 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the October 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is an integer overflow that triggers memory corruption via large values in a subsample of a JPEG image, related to JPEGImageWriter.writeImage in the imageio API.
From the Ubuntu security team
It was discovered that improper checks of unspecified image metadata in JPEGImageWriter.writeImage of the imageio API could allow an attacker to execute arbitrary code with the privileges of the user running a java applet or application.
