Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2025-43214)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in WebKit. A remote attacker can trick the victim into opening a specially crafted file and crash the browser.
2) Input validation error (CVE-ID: CVE-2025-6558)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient validation of user-supplied input in ANGLE and GPU. A remote attacker can trick the victim into opening a specially crafted web page and execute arbitrary code on the system.
Note, the vulnerability is being actively exploited in the wild.
3) Use after free (CVE-ID: CVE-2025-43216)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in WebKit. A remote attacker can trick the victim into opening a specially crafted website and crash the browser.
4) Out-of-bounds read (CVE-ID: CVE-2025-43265)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in WebKit. A remote attacker can trick the victim into visiting a specially crafted website, trigger an out-of-bounds read error and read contents of memory on the system.
5) Memory corruption (CVE-ID: CVE-2025-43211)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in WebKit. A remote attacker can trick the victim into opening a specially crafted file and crash the browser.
6) Memory corruption (CVE-ID: CVE-2025-43212)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in WebKit. A remote attacker can trick the victim into opening a specially crafted file and crash the browser.
7) Memory corruption (CVE-ID: CVE-2025-43213)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in WebKit. A remote attacker can trick the victim into opening a specially crafted file and crash the browser.
8) Insufficient verification of data authenticity (CVE-ID: CVE-2025-43240)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to a logic error, leading to a download's origin being incorrectly associated. A remote attacker can trick the victim into downloading dangerous files from websites that appear ti be trusted.
9) Use-after-free (CVE-ID: CVE-2025-7425)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the xsltSetSourceNodeFlags() function. A remote attacker can pass specially crafted XML input to the application, trigger memory corruption and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
10) Buffer overflow (CVE-ID: CVE-2025-31273)
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 in WebKit. A remote attacker can trick the victim into visiting a specially crafted web page, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
11) Buffer overflow (CVE-ID: CVE-2025-31277)
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 in WebKit. A remote attacker can trick the victim into visiting a specially crafted web page, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) Buffer overflow (CVE-ID: CVE-2025-31278)
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 in WebKit. A remote attacker can trick the victim into visiting a specially crafted web page, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) State issues (CVE-ID: CVE-2025-43227)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a state management issue in WebKit. A remote attacker can trick the victim into opening a specially crafted website and gain access to sensitive information.
14) Spoofing attack (CVE-ID: CVE-2025-43228)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data. A remote attacker can spoof the address bar.
15) Universal cross-site scripting (CVE-ID: CVE-2025-43229)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
16) Improper access control (CVE-ID: CVE-2025-24188)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
