This signature detects attempt to exploit a remote buffer overflow vulnerability in Java Plug-in for Internet Explorer.
Oracle Java SE and Java for Business are prone to a remote vulnerability in the Java plug-in for Internet Explorer.
An attacker can exploit the vulnerability by using a malicious Web page. The vulnerability occurs when the 'docbase' parameter is parsed from an applet. The parameter is copied into a buffer of fixed length on the application's stack. If the parameter exceeds the length allocation to the buffer, a buffer overflow can over, allowing the attacker to corrupt adjacent locations in memory. Due to the buffer overflow, it is possible for an attacker to execute arbitrary code in the context of the currently logged-in user.
This vulnerability affects the following supported versions:
