整数溢出(Integer Overflow)是指在算术运算中,结果超出了整数类型所能表示的最大值或最小值范围。 在C或C++等编程语言中,当执行如加法、减法、乘法等运算时,如果运算结果超出了int类型所能表示的范围(通常是-2,147,483,648到2,147,483,647),就会发生整数溢出。 例如,以下代码会导致整数溢出: c #include <...

Signed addition overflow in C In the following code, thexvariable has the maximumint32_tvalue before the addition, and the result of the addition overflowsx, which the optimizer may not handle in a predictable way: int32_t x = (1U <<31) -1;x +=1;// Error: the add result can't...
integer overflow in express 是什么原因造成的 程序的功能是从键盘输入一个数x，求x的正弦值，然后输出结果。在main()之前的两行称为预处理命令(详见后面)。预处理命令还有其它几种，这里的include 称为文件包含命令，其意义是把尖括号<>或引号""内指定的文件包含到本程序来，成为本程序的一部分。被...

The original vulnerability was an integer overflow leading to a heap-based buffer overflow inUnicodeString::doAppend()in ICU (International Components for Unicode) for C/C++ which existed up to (and including) version 66.1. In the process of validating EDB Postgres Advanced Server 17, a release...
A vulnerability was found in Linux kernel has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel...
