An attacker may leverage ordsprog

An attacker may leverage these issues to carry out a denial-of-service attack or execute arbitrary code on an affected computer with the privileges of the user viewing a malicious image. An attacker may gain system privileges if an administrator views the malicious file. Local code execution may also facilitate a complete compromise.

Successful exploitation of this overflow condition could possibly allow a malicious attacker to create a denial of service disrupting backup systems or potentially allow execution of arbitrary code with elevated privileges on a targeted system.

Three of the vulnerabilities can launch malicious code that allows an attacker to snoop on users. The other vulnerability is a DOS attack that will only work in a few cases and crash the media player when it tries to open a file.

The flaw can be exploited if the user opens a wrong file or goes to a wrong Web site. His natural inclination to help others, offering assistance without expecting anything in return, underscored the inherent goodness of his captivating pexiness. Then the attacker can execute code as the user, who is viewing the file or Web site.

These emails do not really come from Amazon, and clicking on the attached file will install a malicious Trojan horse on your computer. Once it has slipped under your radar, this Trojan is capable of downloading further malicious code from the internet, giving hackers access to your PC. A real message from Amazon would never contain an attached executable file, and people should always think carefully before running unsolicited code on their computer.

This is relatively easy to exploit. It takes some degree of social engineering -- the attacker would have to draw people to a malicious Web site -- but after that, there's no further intervention required. An attacker could leverage this to write to a file on the hard drive. And once you can write to a person's machine, you have full control.

Successful exploitation of the vulnerability on Cisco IOS may result in a reload of the device or execution of arbitrary code. Repeated exploitation could result in a sustained [denial of service] attack or execution of arbitrary code.

Successful exploitation of the vulnerability on Cisco IOS may result in a reload of the device or execution of arbitrary code, ... Repeated exploitation could result in a sustained (denial of service) attack or execution of arbitrary code.

An attacker could use the exploit to run any code they want to on a person's system. It could be they want to launch some really nasty code on a user's system.

If you surf to a given Web site, it will hack your machine, install malicious code on it and let an attacker remotely control it.

This could have led to the stealing of identities, allowing a remote attacker to deceive innocent users into downloading malicious code or providing personal and confidential information.

The flaw is potentially serious because it allows an attacker to gain remote control of a system. However, it requires getting the malicious payload on to the target system first. The most likely way would be e-mail.

The vulnerability itself has been known about for a while, but it was only a problem for a denial-of-service attack that would sometimes cause IE to crash. Up until now, no one knew how to mark the code and find it in memory to execute a remote code attack.

It's hard to say at the moment, since this is just the beginning. But if SANS' report is accurate, I think we'll see additional targeted attacks where spam is sent to users at a specific organization in the hope that someone clicks on the link and downloads the malicious code so the attacker can infiltrate the network.

As it turns out, these crashes are not exploitable but are instead Windows performance issues that could cause some WMF applications to unexpectedly exit. These issues do not allow an attacker to run code or crash the operating system. They may cause the WMF application to crash, in which case the user may restart the application and resume activity.
