Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2024-7519)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error when processing
graphics shared memory. A remote attacker can create a specially crafted
website, trick the victim into opening it, trigger an out-of-bounds read and bypass browser sandbox.
2) Use-after-free (CVE-ID: CVE-2024-7521)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in WebAssembly. A remote attacker can trick the victim to visit 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.
3) Out-of-bounds read (CVE-ID: CVE-2024-7522)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error in editor component. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read and bypass browser sandbox.
4) Security features bypass (CVE-ID: CVE-2024-7524)
The vulnerability allows a remote attacker to bypass CSP policy.
Firefox adds web-compatibility shims in place of some tracking scripts blocked by Enhanced Tracking Protection. On a site protected by Content Security Policy in "strict-dynamic" mode, an attacker able to inject an HTML element could have used a DOM Clobbering attack on some of the shims and achieved XSS, bypassing the CSP strict-dynamic protection.
5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-7525)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due missing permission check when creating a StreamFilter. A web extension with minimal permissions can create a StreamFilter, which can be used to read and modify the response body of requests on any site.
6) Use of uninitialized resource (CVE-ID: CVE-2024-7526)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to usage of uninitialized resources in WebGL ANGLE. A remote attacker can trick the victim to visit a specially crafted website and gain access to sensitive information.
7) Use-after-free (CVE-ID: CVE-2024-7527)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in JavaScript garbage collection. 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.
8) Multiple Interpretations of UI Input (CVE-ID: CVE-2024-7529)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exist due to improper handling of the date picker, which can obscure security prompts. A remote attacker use a malicious site to trick a victim into granting permissions.
9) Cryptographic issues (CVE-ID: CVE-2024-7531)
The vulnerability allows a remote attacker to gain access to sensitive information.
Calling PK11_Encrypt() in NSS using CKM_CHACHA20 and the same buffer for input and output can result in plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header protection feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely outcome is connection failure, but if the connection persists despite the high packet loss it could be possible for a network observer to identify packets as coming from the same source despite a network path change.
