Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Information Exposure Through Timing Discrepancy

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

Description

The 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.

Mitigation

Update the affected package openssl-1_0_0 to the latest version.

2) Use-after-free

EUVDB-ID: #VU71995

Risk: Medium

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-2023-0215

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.

Mitigation

Update the affected package openssl-1_0_0 to the latest version.

3) 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

Description

The 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.

Mitigation

Update the affected package openssl-1_0_0 to the latest version.
