A vulnerability in the 2D component of Oracle Java Runtime Environment could allow an unauthenticated, remote attacker to execute arbitrary code.
The vulnerability is due to insufficient bounds checks on user-supplied raster attributes data. An attacker could exploit the vulnerability by convincing a user to visit a malicious web page. A successful exploit could allow the attacker to execute arbitrary code.
Functional code that demonstrates an exploit of this vulnerability is publicly available.
Oracle has confirmed the vulnerability and released software updates.
Indicators of Compromise
The following Oracle products are vulnerable:
Oracle Java SE JDK and JRE 7 Update 21 and prior
Oracle Java SE JDK and JRE 6 Update 45 and prior
Oracle Java SE JDK and JRE 5 Update 45 and prior
The vulnerability is in the java.awt.image.ByteComponentRaster class due to insufficient bounds checks while copying user-supplied data to the buffer.
An unauthenticated, remote attacker could exploit the vulnerability by convincing a user to visit a malicious web page. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the application.
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.
