and you type in more than 10 characters when the program is run, you will overflow the buffer, causing undefined behaviour. The gets() function has no means of preventing you typing the characters and so should be avoided. Instead you should use fgets(), which allows you to limit the num...
The gets() function provides no support to prevent buffer overflow if large input string are provided. It is defined in <cstdio> header file. Note: Avoid using the gets() function as it can be dangerous for the program. This function was deprecated in C++11 and removed from C++14. gets...
Off-by-one buffer overflow in the sock_gets function in sockhelp.c for ATPhttpd 0.4b and earlier allows remote attackers to execute arbitrary code via a long HTTP GET request. References https://nvd.nist.gov/vuln/detail/CVE-2002-1816 http://archives.neohapsis.com/archives/bugtraq/2002-10...

Linux 下使用C语言 gets()函数报错 在Linux下,使用 gets(cmd) 函数报错:warning: the 'gets' function is dangerous and should not be used. 解决办法:采用 fgets(cmd,100,stdin);//100为size 问题解决! fgets从stdin中读字符,直至读到换行符或文件结束,但一次最多读size个字符。读出的字符连同换行符存入...
Must Read Passing Arrays to Function in C How fgets() and gets() compare to each other? gets() and fgets() are C functions that accept a string with spaces between characters as input. The issue with gets() is that it has a buffer overflow, which means it takes more input than it...
a program, you must first set aside space to store the string and then use an input function ...
The 'gets' function is a vital input function in many programming languages, particularly within the C programming language. Despite its simplicity, 'gets' carries some potential risks and is often criticized for its vulnerability to buffer overflow attacks. However, understanding the fundamentals and...
fgets() function in C The standardClibrary also provides us with yet another function, thefgets()function. The function reads a text line or a string from the specified file or console. And then stores it to the respective string variable. ...
Thegets()function does not perform bounds checking, therefore this function is extremely vulnerable to buffer-overflow attacks. It cannot be used safely (unless the program runs in an environment which restricts what can appear onstdin). For this reason, the function has been deprecated in the ...
