Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2021-21148)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the V8 engine in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, the vulnerability is being actively exploited in the wild.
2) Stack-based buffer overflow (CVE-ID: CVE-2021-21149)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error in Data Transfer in Google Chrome. A remote attacker can trick the victim to visit a specially crafted webpage, trigger a stack-based buffer overflow and execute arbitrary code on the system.
3) Use-after-free (CVE-ID: CVE-2021-21150)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the Downloads component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger use-after-free error and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
4) Use-after-free (CVE-ID: CVE-2021-21151)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the Payments component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger use-after-free error and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
