Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-25735)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in SpiderMonkey when in the way cross-compartment wrappers wrapping a scripted proxy. A remote attacker can execute arbitrary code on the target system.
2) Use-after-free (CVE-ID: CVE-2023-25739)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in mozilla::dom::ScriptLoadContext::~ScriptLoadContext(). Module load requests that failed were not being checked as to whether or not they were cancelled in ScriptLoadContext. A remote attacker can trick the victim to visit 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.
3) Code Injection (CVE-ID: CVE-2023-25751)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation when invalidating JIT code while following an iterator. A remote attacker can trick the victim to visit a specially crafted website and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Buffer overflow (CVE-ID: CVE-2023-29535)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error during Garbage Collector compaction. A remote attacker can create a specially crafted website, 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) Release of invalid pointer or reference (CVE-ID: CVE-2023-29536)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to an invalid free operation from JavaScript code. A remote attacker can trick the victim to visit a specially crafted web page, trigger memory corruption and execute arbitrary code.
6) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2023-29548)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to usage of a wrong lowering instruction in the ARM64 Ion compiler. A remote attacker can gain access to sensitive information.
7) Buffer overflow (CVE-ID: CVE-2023-29550)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing HTML content. A remote attacker can create a specially crafted website, 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.
8) Type Confusion (CVE-ID: CVE-2023-32211)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error when processing HTML content. A remote attacker can trick the victim to open a specially crafted website, trigger a type confusion error and crash the browser.
9) Buffer overflow (CVE-ID: CVE-2023-32215)
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 trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
