Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU67744
Risk: Medium
CVSSv4.0: 4.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-39236
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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
EUVDB-ID: #VU67745
Risk: Medium
CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-39250
CWE-ID:
CWE-345 - Insufficient Verification of Data Authenticity
Exploit availability: No
DescriptionThe 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.

4) Insufficient verification of data authenticity
EUVDB-ID: #VU67743
Risk: Low
CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-39251
CWE-ID:
CWE-345 - Insufficient Verification of Data Authenticity
Exploit availability: No
Descriptionhe 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.
