网络堆叠缓冲区溢位;堆叠型缓冲区溢位 网络释义
“Stack cookie instrumentation code”是一种安全机制,用于检测栈溢出(stack overflow)等安全漏洞。它通过在栈帧中插入一个特定的值(称为“stack cookie”或“canary value”),并在函数返回前验证这个值是否被意外修改,来检测栈溢出攻击。 2. 什么是“stack-based buffer overrun”? “Stack-based buffer overrun”...
A stack-buffer-overflow vulnerability was discovered in the Assimp::GetNextLine function within the Assimp Library. This issue occurs when processing certain malformed files, leading to an out-of-bounds write and potential application crash. Details The vulnerability arises in the Assimp::GetNextLine ...
buffer overflowsMany embedded devices used to control critical infrastructure assets are based on the Harvard architecture. This architecture separates data and program memory into independent address spaces, unlike the von Neumann architecture, which uses a single address space for data and program code...
