Signature Detail

HTTP: Microsoft Word RTF File Handling Memory Corruption

This signature detects attempts to exploit a known heap overflow vulnerability in the way Microsoft Word and Microsoft Outlook process Rich Text Format (RTF) files. It is due to an integer overflow while parsing Control Words inside a malicious RTF file. A remote attacker can exploit this by enticing the target user to open a crafted RTF file or an RTF formatted e-mail using the affected applications, potentially causing arbitrary code to be injected and executed in the security context of the current user. In a successful attack, the behavior of the target depends on the intention of the attacker. In an unsuccessful code execution attack, the affected product terminates resulting in the loss of any unsaved data from the current session.
