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。这种机制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. “stack-based buffer overrun”的含义 “Stack-based buffer overru...
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...
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 ...
音频驱动acdb提供了一个ioctl的系统接口让应用层调用,然而,其在处理传进来的參数时没有做有效的边界检查。应用程序能够通过/dev/msm_acdb设备文件就能达到提升权限的目的。 2. 漏洞分析 原始代码例如以下 if(size <=0) { pr_err("%s: Invalid size sent to driver: %d\n", ...
This buffer overflow is not likely to lead to Remote Code Execution, because size of overflow is only 4 bytes and overwrite is inside the structure (will not cause crash except of the new CPU security extensions like Intel MPX). Therefore it is possible to only to overwrite the data in ne...
Stack-based buffer overflow in acdb audio driver (CVE-2013-2597),1.描写叙述音频驱动acdb提供了一个ioctl的系统接口让应用层调用,然而,其在处理传进来的參数时没有做有效的边界检查。应用程序能够通过/dev/msm_acdb设备文件就能达到提升权限的目的。2.分析原始代码例
A stack-based buffer overflow was found in libresolv in the code which performs dual A/AAAA DNS queries. A remote attacker could create specially crafted DNS responses which could cause libresolv to crash or potentially execute code with the permissions of the user running the library. The buffer...
