Description
This security bulletin contains information about 19 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2024-43097)
The vulnerability allows a local application to execute arbitrary code.
The vulnerability exists due to improper input validation within the System component. A local application can execute arbitrary code.
2) Use-after-free (CVE-ID: CVE-2025-1931)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in WebTransportChild. A remote attacker can trick the victim into visiting a specially crafted website, trigger a use-after-free in the content process side of a WebTransport connection and execute arbitrary code on the system.
3) Out-of-bounds write (CVE-ID: CVE-2025-1932)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to inconsistent comparison in xslt/txNodeSorter. A remote attacker can trick the victim into visiting a specially crafted web page, trigger an out-of-bounds write and execute arbitrary code on the target system.
4) Buffer overflow (CVE-ID: CVE-2025-1933)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error on 64-bit CPUs, when the JIT compiles WASM i32 return values they can pick up bits from left over memory. 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.
5) Resource management error (CVE-ID: CVE-2025-1934)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application. A remote attacker interrupt the processing of a RegExp bailout and run additional JavaScript, potentially triggering garbage collection when the engine was not expecting it.
6) Improper Restriction of Rendered UI Layers or Frames (CVE-ID: CVE-2025-1935)
The vulnerability allows a remote attacker to perform clickjacking attack.
The vulnerability exists due to the way the registerProtocolHandler info-bar handles events. A remote attacker can trick the victim into setting a malicious site as the default handler for a custom URL protocol.
7) Input validation error (CVE-ID: CVE-2025-1936)
The vulnerability allows a remote attacker to bypass security restrictions.
The vulnerability exists due to insufficient validation of a null-byte character (e.g. %00) in the filename when retrieving local file content packaged in a ZIP archive via jar: URLs. The null and everything after it is ignored when retrieving the content from the archive, but the fake extension after the null is used to determine the type of content. A remote attacker can hide code in a web extension disguised as a safe file, such as an image.
8) Buffer overflow (CVE-ID: CVE-2025-1937)
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 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.
9) Buffer overflow (CVE-ID: CVE-2025-1938)
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 into visiting 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.
10) Security features bypass (CVE-ID: CVE-2025-1941)
The vulnerability allows a remote attacker to bypass the lock screen.
The vulnerability exists due to the way notifications are handled on a locked screen. Under certain circumstances a user opt-in setting that Focus should require authentication before use can be bypassed, resulting in unauthorized access to the browser.
11) Information disclosure (CVE-ID: CVE-2025-1942)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application within the String.toUpperCase() function, which includes parts of uninitialized memory into the result output. A remote attacker can gain unauthorized access to sensitive information.
12) Buffer overflow (CVE-ID: CVE-2025-1943)
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 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) Use-after-free (CVE-ID: CVE-2025-3028)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in XSLTProcessor. A remote attacker can trick the victim into visiting 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.
14) Spoofing attack (CVE-ID: CVE-2025-3029)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of non-BMP unicode characters. A remote attacker can use a specially crafted URL to spoof the URL bar in the browser.
15) Buffer overflow (CVE-ID: CVE-2025-3030)
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 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.
16) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2025-3031)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a JIT optimization error. A remote attacker can read 32 bits of values spilled onto the stack in a JIT compiled function.
17) Memory leak (CVE-ID: CVE-2025-3032)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due browser leaks file descriptors from the fork server to web content processes. A local user can use this information to escalate privileges on the system.
18) Buffer overflow (CVE-ID: CVE-2025-3034)
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 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.
19) Information disclosure (CVE-ID: CVE-2025-3035)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the tab title can be leaked when using the AI chatbot in one tab and later activating it in another tab. A remote attacker can gain access to title of a previous tab.
