CVE-2022-1634 After free in the Browser UI of Google Chrome prior to 101.0.4951.64 allowed a remote attacker to exploit heap corruption.

CVE-2022-1634 After free in the Browser UI of Google Chrome prior to 101.0.4951.64 allowed a remote attacker to exploit heap corruption.

CVE-2018-4878 was discovered by Gary Steele. After the heap corruption occurs, the attacker can force the browser to crash or execute arbitrary code by triggering the interaction with the user. To have the user perform specific actions, the attacker can persuade the user to follow a malicious link, open a malicious file, visit a malicious website, or reload an application that was previously exploited. After the heap corruption occurs, the attacker can force the browser to crash or execute arbitrary code by triggering the interaction with the user. To have the user perform specific actions, the attacker can persuade the user to follow a malicious link, open a malicious file, visit a malicious website, or reload an application that was previously exploited. For the exploit to work, the attacker needs to convince a user to follow the malicious link, open a malicious file, visit a malicious website, or reload an application that was previously exploited. End users can protect themselves from this vulnerability by following safe browsing practices, such as avoiding clicking on links in unsolicited emails, avoiding opening unverified files, and staying vigilance of their browsing activity. Users can also seek out information on how to secure their systems against drive-by-attack, such as downloading and installing anti-malware software on their systems, keeping their software up to date, and avoiding visiting websites that have been flagged as dangerous.

Vulnerability description

The vulnerability is caused by a heap overflow error. It allows the attacker to execute arbitrary code on the system by triggering the interaction with the user.
If an attacker is able to convince a user to follow a malicious link, open a malicious file, visit a malicious website, or reload an application that was previously exploited, then he/she can exploit this vulnerability and escalate privileges on the system.

Heap Corruption

The vulnerability can be exploited by persuading the user to follow a malicious link, open a malicious file, visit a malicious website, or reload an application that was previously exploited. To have the user perform specific actions, the attacker can persuade the user to follow a malicious link, open a malicious file, visit a malicious website, or reload an application that was previously exploited. For this exploit to work, the attacker needs to convince a user to follow the malicious link.

Vulnerability details

The vulnerability was discovered by Gary Steele, a security researcher at Azimuth Security and was first announced on July 25, 2018. The vulnerability has been assigned the CVE-2018-4878 identifier. The vulnerability is a heap corruption bug in the rendering of PDF documents in Google Chrome and can allow attackers to execute arbitrary code on the system if the user interacts with it. An attacker needs to convince a victim to do something that will trigger this issue before they can exploit it.

Vulnerability Scenario

If you have a website that uses PHP, you can protect your users from this vulnerability by using the following techniques:
- Use an intrusion prevention system (IPS) or similar software to prevent common exploits from running on your website.
- Do not use MySQL's default settings for storage and connections.
- Ensure that any version of PHP you are using is up to date.
