The vulnerability allows a remote attacker to perform a spoofing attack.
The vulnerability exists due to insufficient validation of user-supplied input in Web App Installs in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it and spoof web page content.
2) Improperly implemented security check for standard (CVE-ID: CVE-2021-30507)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to incorrect implementation in Offline in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it and compromise the system.
3) Heap-based buffer overflow (CVE-ID: CVE-2021-30508)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in Media Feeds. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
4) Out-of-bounds write (CVE-ID: CVE-2021-30509)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in Tab Strip. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger out-of-bounds write and execute arbitrary code on the target system.
5) Race condition (CVE-ID: CVE-2021-30510)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a race condition in Aura in Google Chrome. A remote attacker can trick the victim to visit a specially crafted webpage and execute arbitrary code on the target system.
6) Out-of-bounds read (CVE-ID: CVE-2021-30511)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the Tab Groups component in Google Chrome. A remote attacker can trick the victim into visiting a specially crafted web page, trigger an out-of-bounds read error and gain access to sensitive information.
7) Use-after-free (CVE-ID: CVE-2021-30512)
