Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-3266)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary condition when decoding H264 video. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger an out-of-bounds read error and execute arbitrary code on the target system.
2) Input validation error (CVE-ID: CVE-2022-39236)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when processing beacon events. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Insufficient verification of data authenticity (CVE-ID: CVE-2022-39249)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to a very permissive key forwarding strategy. A remote attacker cooperating with a malicious home server can construct messages appearing to have come from another person.
4) Insufficient verification of data authenticity (CVE-ID: CVE-2022-39250)
The vulnerability allows a remote attacker to bypass SAS verification.
The vulnerability exists due to checking and signing user identities and devices in two separate steps, and inadequately fixing the keys to be signed between these steps. A remote attacker cooperating with a malicious home server can interfere with the verification flow between two users, injecting its own cross-signing user identity in place of one of the users’ identities, leading to the other device trusting/verifying the user identity under the control of the home server instead of the intended one.
5) Insufficient verification of data authenticity (CVE-ID: CVE-2022-39251)
he vulnerability allows a remote attacker to bypass implemented security restrictions.The vulnerability exists due to a protocol confusion vulnerability that accepts to-device messages encrypted with Megolm instead of Olm. A remote attacker cooperating with a malicious home server can construct messages appearing to have come from another person without any indication such as a grey shield.
6) Security features bypass (CVE-ID: CVE-2022-40956)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to some requests may ignore the CSP's base-uri settings when handling HTML base element injection. A remote attacker can force the browser to accept the injected element's base instead of the original code, leading to Content Security Policy bypass.
7) Input validation error (CVE-ID: CVE-2022-40957)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to inconsistent data in instruction and data cache when creating wasm code. A remote attacker can trick the victim to open a specially crafted web page, trigger memory corruption and potentially execute arbitrary code.
Note, the vulnerability affects Firefox on ARM64 platforms only.
8) Security features bypass (CVE-ID: CVE-2022-40958)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to incorrect handling of cookies. A remote attacker with access to a shared subdomain can inject a cookies with certain special characters, bypass Secure Context restriction for cookies with __Host and __Secure prefix and overwrite these cookies, potentially allowing session fixation attacks.
9) Security features bypass (CVE-ID: CVE-2022-40959)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to incorrect initialization of FeaturePolicy on all pages during iframe navigation. A remote attacker can trick the victim to open a specially crafted website, bypass FeaturePolicy restrictions and force the browser to leak device permissions into untrusted subdocuments.
10) Use-after-free (CVE-ID: CVE-2022-40960)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error caused by a concurrent use of the URL parser with non-UTF-8 data. 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.
11) Buffer overflow (CVE-ID: CVE-2022-40962)
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.
12) Security features bypass (CVE-ID: CVE-2022-42927)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to same-origin policy violation in the performance.getEntries() method. A remote attacker can trick the victim to open a specially crafted website and gain obtain cross-origin URL entries.
13) Buffer overflow (CVE-ID: CVE-2022-42928)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Garbage Collector within the JS engine. 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.
14) Resource management error (CVE-ID: CVE-2022-42929)
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 when handling window.print() events. A remote attacker trick the victim to open a specially crafted website and perform a denial of service (DoS) attack.
15) Buffer overflow (CVE-ID: CVE-2022-42932)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling 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.
