Ubuntu update for nodejs

1) Infinite loop

EUVDB-ID: #VU61391

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-0778

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: Yes

Description

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

The vulnerability exists due to infinite loop within the BN_mod_sqrt() function when processing an ASN.1 certificate that contains elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. A remote attacker can supply a specially crafted certificate to the TLS server or client, consume all available system resources and cause denial of service conditions.

Mitigation

Update the affected package nodejs to the latest version.

2) 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 nodejs to the latest version.

EUVDB-ID: #VU64559

Risk: Medium

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2068

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.

The vulnerability exists due to incomplete fix for #VU62765 (CVE-2022-1292).

Mitigation

Update the affected package nodejs to the latest version.

4) 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 nodejs to the latest version.
