Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
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.

The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU71993
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4304
CWE-ID:
CWE-208 - Information Exposure Through Timing Discrepancy
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain sensitive information.
The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.
To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4450
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the PEM_read_bio_ex() function. A remote attacker can pass specially crafted PEM file to the application, trigger a double free error and perform a denial of service (DoS) attack.
