That sort of overflow can be avoided if the program includes sufficient bounds checking to flag or discard data when too much is sent to a memory buffer. Buffer overflows are among the most persistent and dangerousvulnerabilities in software, often exploited by attackers to gain unauthorized access...
the buffer rests on the thing that causes input to be generated. If some user runs a command-line program he can cause to segfault by feeding a more than a certain amount of data into it, that's kind-of ugly and certainly not a sensible interface design for application programs ...
Oh, and a factoid (that drove me crazy in my early QoS endeavors, as I didn't initially know), Cisco interfaces often have a hardware FIFO queue, and it's only its overflow that can obtain its prioritized dequeuing by a QoS policy. (NB: what drove me crazy,...
If you do not want to keep a slow loading add-on around, you can disable it, and it won’t be loaded the next time you open a new window or tab. You can also open Add/Remove Programs and remove IE add-ons that you are not using. This removes the add-on for all users on ...
How can this allocation for synchronous completions be avoided more generally in situations where the performance overhead really matters?That’s where ValueTask<TResult> comes into the picture (a much more detailed examination of ValueTask<TResult> is also available). ValueTask<TResult> started ...

Vulnerabilities can be avoided by using different methods of validation and verification of software, including static analysis. This article will cover the topic of how PVS-Studio copes with the task of vulnerability search.PVS-Studio is a Tool that Prevents not Only Bugs, but also Vulnerabilities...
First of all: Divide by zero is NOT a catchable C++ exception! That is a program bug and should be avoided (such as by sanitizing input with an if statement like Marcus demonstrated).If you need, for some reason, to catch Win32 exceptions, such as access violations and divide by zero ...
OpenGL not only allows you to draw to the screen, but also to textures (through a concept called a framebuffer). So we can encode the particle position as the RGBA color of the image, load it into the GPU, calculate the new position in the patch shader based on the wind speed, re-...
