A vulnerability in the java.awt.image.IntegerComponentRaster class could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system with the privileges of the targeted user.
The vulnerability is due to improper boundary restrictions on input processed by the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to view a website that contains a malicious Java applet.
Oracle has confirmed the vulnerability in a security bulletin and released software updates.
Indicators of Compromise
Java SE JDK and JRE 7 Update 21 and prior, JDK and JRE 6 Update 45 and prior, JDK and JRE 5.0 Update 45 and prior, and JavaFX 2.2.21 and prior are vulnerable.
The vulnerability is due to improper boundary restrictions by the java.awt.image.IntegerComponentRaster class within Java.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to view a malicious applet that attempts to send overly large input to the vulnerable class object. The processing of the overly large input could trigger a buffer overflow condition that the attacker could leverage to execute arbitrary code on the targeted system with the privileges of the targeted user.
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
This vulnerability was corrected in the Oracle Java SE Critical Patch Update June 2013 as documented in Alert 29704.
