PrefaceLast time we discussed the principle of buffer overflow, and this time we need to use this principle to construct conditions to exploit this vulnerability.In fact, the use of buffer overflow vulnerability is mainly to solve the following three problems:1. Pinpoint the location of the return address2. Find a suitable address for overwriting the original return address3, write shellcode to the correspo

The file_get_contents () function reads the entire file into a string.Like file (), the difference is that file_get_contents () reads the file into a string.The file_get_contents () function is the preferred method for reading the file content into a string. If supported by the operating system, the memory ing technology will be used to enhance the performance.SyntaxFile_get_contents (path, include_path, context, start, max_length)*/Ob_start (); // open the bufferEcho "hello"; // Outpu

SQL Server Ring Buffer--relationship between SQL Server and ring bufferThe SQL Server operating system (SQLOS) is responsible for managing SQL Server-specific operating system resources. One of the related dynamic management attempts sys.dm_os_ring_buffers will be identified as informational only. No support is provided. No future compatibility is guaranteed.First look at the different ring buffer types rec

Refresh the PHP buffer for your site acceleration, refresh the PHP buffer site In the current PHP version of the default configuration, "Output buffering" is opened. The old version is not so, in the old version of PHP, the string at each time the output (through the Echo or print function), will trigger a send to the client browser action.The introduction of "Output buffering" makes this process faster an

When the server process scans the LRU primary column, it moves the dirty block to the Lruw column. When scanned to a threshold (10g/11g is the 40%-_db_block_max_scan_pct parameter decision) will stop the scan and notify DBWR write dirty block-write dirty block after the block back to the auxiliary LRU column, get free buffer. DBWR Process write dirty block before completion, the server process waits for free buff
