# re: Buffer OverflowsIt's different because in this case the application is giving the OS the correct size of the buffer, so it will not write too much data.In a real security risk overrun, the application will usually assume a buffer size that is large enough, which means if it ...
The buffer overflow has long been a feature of the computer security landscape. In fact the first self-propagating Internet worm—1988's Morris Worm—used a buffer overflow in the Unixfingerdaemon to spread from machine to machine. Twenty-seven years later, buffer overflows remain a source of ...

1. Buffer Overflow Attack [45 pts + optional bonus 15 pts ] 1.1 Turning off Countermeasures Before starting this lab, we need to make sure the address randomization countermeasure is turned off; otherwise, the attack will be difficult. You can do it using the following command: ...
I've been fuzzing different pytorch modules with with [sydr-fuzz](https://github.com/ispras/oss-sydr-fuzz/tree/master/projects/pytorch), and found a heap buffer overflow error that occures by incorrect loop condition in torch::jit::unpickler.cpp. This bug was found in several fuzzing ...
As part of our platform research in Zimperium zLabs, we recently disclosed a buffer overflow vulnerability affecting multiple Android DRM services to Google. Google classified it as high-severity, designated it as CVE-2017-13253 and have patched it in theMarch security update. ...
