Signature Detail

HTTP: Microsoft Internet Explorer HTML Objects Memory Corruption (CVE-2009-1918)

This signature detects attempts to exploit a known memory corruption vulnerability in Microsoft Internet Explorer. It is due to the way Internet Explorer handles table operations in specific situations. An attacker can persuade the target user to open a malicious web page to exploit this vulnerability. In an attack scenario, where arbitrary code is injected and executed on the target system, the behaviour of the target is dependent on the intention of the malicious code. The injected code will be run with privileges of the currently logged on user. If such an attack is not executed successfully, the vulnerable application may terminate as a result of invalid memory access.

Extended Description

Microsoft Internet Explorer is prone to a remote code-execution vulnerability. Attackers can exploit this issue to execute arbitrary code in the context of the user running the browser. Successful exploits will compromise the browser and possibly the computer. Failed attacks may cause denial-of-service conditions.
