Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Inadequate Encryption Strength

EUVDB-ID: #VU68116

Risk: Medium

CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:F/RL:O/RC:C]

CVE-ID: CVE-2022-3358

CWE-ID: CWE-326 - Inadequate Encryption Strength

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to decrypt traffic.

The vulnerability exists due to an error in openssl implementation when handling legacy custom ciphers with NID_undef passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() functions. Under certain conditions openssl can fail to select a proper cipher and use NULL instead, which corresponds to sending data in plain text.

Note, applications are only affected by this issue if they call EVP_CIPHER_meth_new() using NID_undef and subsequently use it in a call to an encryption/decryption initialisation function.

Mitigation

Update the affected package openssl-3 to the latest version.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, a fully functional exploit for this vulnerability is available.

2) Buffer overflow

EUVDB-ID: #VU68895

Risk: High

CVSSv3.1: 7.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-3602

CWE-ID: CWE-119 - Memory corruption

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing the email address field inside X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a 4-byte buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that either a CA signs the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.

Mitigation

Update the affected package openssl-3 to the latest version.

3) Buffer overflow

EUVDB-ID: #VU68896

Risk: Medium

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-3786

CWE-ID: CWE-119 - Memory corruption

Exploit availability: Yes

Description

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

The vulnerability exists due to a boundary error when processing the email address field length inside a X.509 certificate. A remote attacker can supply a specially crafted certificate to the application, trigger a buffer overflow and crash the application.

Mitigation

Update the affected package openssl-3 to the latest version.
