Last night, the black pot posted a foreigner-exposed Nginx vulnerability on Weibo, and few people started to pay attention to it. I tested and verified the installation environment, I tried two websites on the Internet and verified the vulnerability, So I uploaded the vulnerability on Weibo immediately.
This vulnerability was launched in July 20. Foreigners have made a very detailed analysis. For more information, see:

First, we can see from the main function that the key explanation has been annotated. This function is in the FFMPEG. c file. The Code is as follows:
Int main (INT argc, char ** argv) {int ret; int64_t Ti; // registers the cleaning callback function register_exit (ffmpeg_cleanup); setvbuf (stderr, null, _ ionbf, 0);/* Win32 ru
(2*34+2) when appended to 34 characters. Whatever it takes to reach its maximum capacity it will have to create a new character array and then stringbuffer the old and new characters again-which is too expensive. So it's wrong to always set a reasonable initialization capacity value for StringBuffer, which can result in immediate performance gains. The role of the adjustment of the StringBuffer initializat

Decide when to add a type declaration:
Because static typing is often the key to large speed gains, beginners often, have a tendency to type everything in sight. This both readability and flexibility and can even slow things-e.g. by adding unnecessary type checks, conversions, or slow buffer unpacking). On t
