Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) 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.
2) Out-of-bounds read (CVE-ID: CVE-2023-25752)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when accessing throttled streams. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.
3) Type conversion (CVE-ID: CVE-2023-28162)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an invalid downcast in AudioWorklets. A remote attacker can trick the victim to open a specially crafted web page and execute arbitrary code on the system.
4) Information disclosure (CVE-ID: CVE-2023-28163)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application when downloading files through the Save As dialog on Windows with suggested filenames containing environment variable names. A remote attacker can gain unauthorized access to sensitive information on the system.
Note, the vulnerability affects only Windows installations.
5) Spoofing attack (CVE-ID: CVE-2023-28164)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data when dragging a URL from a cross-origin iframe. A remote attacker can spoof page content.
6) Buffer overflow (CVE-ID: CVE-2023-28176)
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 conent. 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.
7) Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') (CVE-ID: CVE-2023-28427)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a prototype pollution issue in Matrix SDK. A remote attacker can pass specially crafted input with events containing special strings in key locations and perform a denial of service (DoS) attack.
