Rekindle 2003

Chapter 344

"Dean Qin, I discovered a vulnerability in our QiChaCha software last night."

Qing Yun, who had swallowed the egg yolk and was about to say something to chase people away, choked in his throat. He immediately bent over and coughed. Tang Qianying and Qin Manman opposite him were startled and quickly brought him tissues.

A stuck egg yolk is no joke.

Su Caiwei snickered in her heart, it is true that reincarnation happens in the way of heaven!

Isn’t this your favorite trick?
Today the teacher will teach you a lesson!
Su Caiwei has always been worried about the fact that Qing Yun played this trick on her and Shi Guangyong again and again during the last visit. Today, she saw the right opportunity and used the same method to teach this bad student. What? It's called 'empathy'!
However, she still had a look of panic on her face, and she patted his back helplessly.

She was the closest, so neither Qin Manman nor Tang Qianying said anything. They just stood up and looked worriedly.

The movement was a bit loud, which naturally attracted the attention of people in the restaurant.

However, after a few glances, everyone turned their heads and ate their breakfast indifferently.

Too cruel.

A cough, three charming beauties are eagerly waiting for you, this life...

Choking to death, you deserve it!

After a while, Qing Yun drank hard, sneezed twice more before she could breathe again, and looked at Su Caiwei with unkind eyes.

He didn't know if she did it on purpose, but he knew that Teacher Xiao Su had no good intentions.

When he hit his back, it was obvious that he was doing something serious.

Ha ha!

It's hard to defend against me when you're playing a secret game, right?
Don't let me take a chance!

Su Caiwei understood his look and smiled secretly in her heart, but her eyes showed a look of fear and uneasiness, and she spoke with a sense of grievance, "I'm sorry, classmate Xiaoqing, I was in a hurry just now. Yeah, I couldn’t control my strength well.”

Qing Yun nodded, "What loophole did you just say?"

He was too lazy to talk nonsense to her, and quietly glanced at Su Caiwei's waist and hips, and then quickly suppressed the evil fire in his heart.

Teacher Xiao Su's figure is really a bit foul.

And unlike Tang Qianying and Chen Yue, Su Caiwei is a few years older after all, and like Qin Manman, who is already a woman, her figure is more mature and rounded.

Pity!
What a pity!

Su Caiwei ignored him and turned to look at Qin Manman, "Last night when I was reading the source code of the Qichacha software, I found a loophole in the buffer.

Our programmers usually assign a certain byte buffer to the function, such as this. "

She took out the notebook she carried with her...

Paper notebook.

This startled Qing Yun.

What surprised him was Su Caiwei and Qin Manman.

Can they not read it on a computer or use a compiler?
This somewhat subverted his cognition.

Could it be that the jokes on the Internet are true?
"Power outage? When there is a power outage, don't you write the code with pen and paper first, and then input it into the computer after the call comes in? Isn't it, is it difficult? Is my request too much?" - Lin'an Ma.

Well, programmers from the 90s do have this skill.

At that time, computers were not yet popular among the public. If you wanted to program, the best way was to go to the school computer room. However, the school computer room was also expensive, and not all computer rooms were free.Therefore, at that time, many programmers could only buy a notebook, pick up a pen, write the code, and finally go to the computer room to input, debug, and run. This could save a lot of money.

However, at the turn of the century, computers gradually changed from a high-tech product to a household appliance, so this skill was basically lost.

It was only in another ten years that the major Internet companies used this magic weapon again in order to screen people.

In Emperor Yun's understanding, Qin Manman and Su Caiwei definitely do not belong to the group of people who cannot afford computers, so...

This is such a powerful basic skill.

Qin Manman took the notebook, glanced at it twice, and frowned instantly, "When executing int verify_password (char *password), if a stack overflow is used, there will be problems."

Su Caiwei nodded, "If the password we enter exceeds the specified characters, the ASCII code of the out-of-bounds characters will modify the authenticated value. If this overflow data happens to change authenticated to 0, the program flow will be changed. In this way, You can successfully use an illegal long password to modify the buffer's adjacent variable authenticated, thus bypassing the password verification program..."

Qing Yun and Tang Qianying on the side could only compare the size of their eyes. They said they didn't understand, not at all.

This is not an area they should be exposed to.

Qin Manman understood it, took Su Caiwei's pen and started drawing, and then started discussing in a low voice with Su Caiwei.

Emperor Yun and Lord Qianying could understand every word in their mouths, even in English, but when combined, they thought the two women were just talking in bird language to bully others.

The bored two people could only do small tricks secretly under the table.

The movement should not be too big, so as not to affect the empress who has already entered into working mode.

Mainly, this is business.

After grasping the main contradiction, Qing Yun still roughly understood what they were talking about.

It is the password verification system of Qichacha software that has a loophole and is easily broken.

He thought about it and knew what was going on.

In the past, TOP, when making software, usually made stand-alone versions or intranet versions, so there was no need to consider this issue.

But the current requirement is for an online version, and the shortcomings of the stand-alone version in the Shishan code have been ignored.

At this moment, what he needs to consider is whether to take advantage of the opportunity and give the programmers in the software academy a killing blow.

Although he also understands that this kind of old code, which is called shit mountain in the industry, is not as easy to change as imagined.

In fact, among programmers, there is a common view: Don't move the code if it can run.

As the saying goes, a single move can affect the whole body. If the code does not move well, it will cause "the shit collapses and the mountain breaks apart".

Although it is a secondary development of old software, under his time limit, everyone must be lazy as much as possible, but times have changed.

The biggest difference is the difference between stand-alone software and network software.

If security is not taken into consideration and the company's software is positioned for government agencies, the Yanhuang Group will not reap the rewards.

After Qin Manman and Su Caiwei finished discussing the revised plan, Qing Yun nodded on the table and looked at Qin Manman with a serious face, "Catch him and be ruthless. If necessary, you can kill a few people to scare the monkeys."

Before Qin Manman said anything, Su Caiwei panicked, "Mr. Xiaoqing, it's not necessary. It's just a small problem."

When she mentioned this flaw, her original intention was to pass the breakfast by acting to pass the time, thereby causing other people's misunderstanding.

However, now that she was about to cause others to be fired, her conscience was very disturbed.
