Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) 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.
2) Use-after-free (CVE-ID: CVE-2025-1930)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the Browser process when handling StreamData sent over AudioIPC. A remote attacker can trick the victim into visiting a specially crafted web page and execute arbitrary code on the system.
The vulnerability affects Firefox installations on Windows only.
3) 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.
4) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
