Discussion
Sun Java RunTime Environment GIF Images Buffer Overflow Vulnerability
The Java Runtime Environment is prone to a buffer-overflow vulnerability because the application fails to bounds-check user-supplied data before copying it into an insufficiently sized memory buffer.
An attacker may exploit this issue by enticing a victim into opening a maliciously crafted Java applet.
The attacker can exploit these issues to execute arbitrary code with the privileges of the victim. Failed exploit attempts will likely result in denial-of-service conditions.
This issue is being tracked by BugID: 6445518
