Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2022-1097)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when handling NSSToken objects. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Use-after-free (CVE-ID: CVE-2022-1196)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content after the VR Process is destroyed. A remote attacker can trick the victim to visit a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
3) Spoofing attack (CVE-ID: CVE-2022-28286)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data. Due to a layout change, iframe contents can be rendered outside of its border. A remote attacker can spoof page content.
4) Buffer overflow (CVE-ID: CVE-2022-28289)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Resource exhaustion (CVE-ID: CVE-2022-24713)
The vulnerability allows a remote attacker to perform a denial of service (ReDoS) attack.
The vulnerability exists due regex for Rust does not properly control consumption of internal resources when parsing untrusted input. A remote attacker can pass specially crafted data to the application and perform a regular expression denial of service (ReDoS) attack.
6) Use-after-free (CVE-ID: CVE-2022-28282)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing links with rel="localization". A remote attacker can trick the victim to open a specially crafted web page, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
7) Out-of-bounds write (CVE-ID: CVE-2022-28281)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when handling an unexpected number of WebAuthN Extensions in a Register command to the parent process. A remote attacker can create a specially crafted web page, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
8) Resource management error (CVE-ID: CVE-2022-28285)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to usage of incorrect AliasSet when generating the assembly code for MLoadTypedArrayElementHole. A remote attacker can abuse this along with another vulnerability to perform an out-of-bounds read.
