Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Error Handling
EUVDB-ID: #VU72036
Risk: Low
CVSSv3.1: 2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-23931
CWE-ID:
CWE-388 - Error Handling
Exploit availability: No
DescriptionThe vulnerability allows an attacker to misuse Python API.
The vulnerability exists due to a soundness bug within the Cipher.update_into function, which can allow immutable objects (such as bytes) to be mutated. A malicious programmer can misuse Python API to introduce unexpected behavior into the application.
Install update from vendor's website.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
The attacker would have to login to the system and perform certain actions in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Type Confusion
EUVDB-ID: #VU71992
Risk: High
CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-0286
CWE-ID:
CWE-843 - Type confusion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
