partial or total control over a host. If buffer overflow vulnerabilities could be effectively eliminated, a very huge portion of security threats would also be addressed. There are several basic methods to protect the buffer from buffer overflow attacks and impacts. The specific methods are as ...
Buffer overflow attacks caused some of the most infamous hacking examples,from the Morris Worm in 1998 to Stagefright in 2015. Let's explain how they work, and we'll help you understand how to protect yourself from them. What Is a Buffer Overflow? Almost every computer has a buffer. This...
It supports checking attribute values for minimum/maximum length and minimum/maximum value, to protect against Buffer Overflows and Denial of Service attacks against WWW clients and various servers. You can stop from having too high values for width and height, for instance, It has got a syste...
And, notably, it turns your computer into a clickfarm to secretly generate video revenue and YouTube subscribers. Protect your devices with anti-rootkit software Trusted by over 400 million users around the world, Avast defends against all types of malware, including rootkits. When you install ...
OpenSSL has announced two severe vulnerabilities. Learn how to respond to them and protect your business from falling victim to their exploitation..
Dangling pointers occur when a programmer creates, uses and then frees an object in memory but does not change the object's pointer value accordingly -- in this case, to a null pointer. Instead, the pointer inaccurately refers to the memory location of the deal...
Like many others here, I am eagerly awaiting a resolution. I am looking for interim advice on how to mitigate this vulnerability until an official patch is released. Has anyone implemented any successful workarounds or additional security measures to protect against potential exploits...
How do you protect against IP spoofing? IP spoofed packets can't be eliminated. But organizations can take measures to protect their networks and data. Here are some steps companies can take: Use strong verification and authentication methods for all remote access. Do not authenticate devices and...
Worms exploit other files and programs to do the dirty work. For example, the SQL Slammer worm used a (patched) vulnerability in Microsoft SQL to incur buffer overflows on nearly every unpatched SQL server connected to the internet in about 10 minutes, a speed record that still stands today...
And now for something completely different! Welcome to the land of Systems Architecture. In cool leg, we teach CS undergrads to protect their multi-threaded data structures with a lock. This is probably a Test-and-Set (TAS) lock, and if they went to a good university, they have a homewo...
