Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) Buffer overflow (CVE-ID: CVE-2025-24189)
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 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) 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.
6) Spoofing attack (CVE-ID: CVE-2025-43228)
