The device is thought to be protected by the use of W [R] X policy and the attacker can't insert arbitrary executable code
in the stack or the heap.

The same strategy lies at the heart of San Ramon, CA-based Faronics' literally named filtering tool, Anti-Executable, designed specifically to shield school computers from malicious executable code
. The product works from a white list, a roster of authorized programs that district tech managers and IT administrators control.
As part of this major SandBox release, SandBox Analyzer products now have the ability to not only detect and analyze executable code
, but also exploit code concealed in Microsoft Office as well as other popular exploitable file formats.
You can get malware from graphics files, music files, document files and pretty much anything else capable of carrying a form of executable code
. If you want a truly frightening picture of the ratio of bad to good applications, take a look at the list your antivirus software uses to identify malicious code.
Unlike traditional approaches, ESET solutions decode and analyse executable code
in real-time, using an emulated environment.
Once installed on a computer, it reads every bit of executable code
on that unit to determine a profile for that computer.
Examples of specific topics include a stochastic model for video and its information rates, spatial sparsity induced temporal prediction for hybrid video compression, differential compression of executable code
, parallel decoding for lossless image compression by block matching, high throughput compression of double- precision floating-point data, and Bayesian detection in bounded height tree networks.
The device is available as either a callable function which is integrated into an OEM's framework, or as a standalone DSP image of executable code
MySpace, and Skype, has depended on the creators' ability to send executable code
as well as data to the user's personal computer.
The reality, the association pointed out, is that tag contents are never interpreted as executable code
but are interpreted only as simple raw data.
"Companies are best protected by automating their anti-virus protection and putting a policy in place at their email gateway to block unsolicited executable code
from the outside world."
