Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) OS Command Injection

EUVDB-ID: #VU62765

Risk: Medium

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-2022-1292

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Exploit availability: No

Description

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

The vulnerability exists due to improper input validation in the c_rehash script distributed by some operating systems. A remote attacker with ability to pass data to c_rehash script can and execute arbitrary OS commands with the privileges of the script.

Mitigation

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

2) Security features bypass

EUVDB-ID: #VU62766

Risk: Medium

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1343

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error when validating OCSP response within the OCSP_basic_verify function. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. A remote attacker can perform MitM attack.

Mitigation

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

3) Man-in-the-Middle (MitM) attack

EUVDB-ID: #VU62767

Risk: Low

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1434

CWE-ID: CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists in OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite due to incorrect usage of AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker can perform a man-in-the-middle (MitM) attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the modified data would still pass the MAC integrity check.

Mitigation

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

4) Uncontrolled Memory Allocation

EUVDB-ID: #VU62768

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1473

CWE-ID: CWE-789 - Uncontrolled Memory Allocation

Exploit availability: No

Description

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

The vulnerability exists due to memory reuse is not possible in the OPENSSL_LH_flush() function, which empties a hash table when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will expand without bounds and the process might be terminated by the operating system causing a denial of service.

Mitigation

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

6) Missing Encryption of Sensitive Data

EUVDB-ID: #VU64922

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2097

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error in AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation. Under specific circumstances OpenSSL does not encrypt the entire message and can reveal sixteen bytes of data that was preexisting in the memory that wasn't written. A remote attacker can gain access to potentially sensitive information.

Mitigation

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