Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU61391

Risk: Medium

CVSSv4.0: 7.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]

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

Install update from vendor's website.

2) Access control error

EUVDB-ID: #VU380

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-6329

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows attackers to gain access to potentially sensitive information.

The vulnerability exists due to capturing of long duration Blowfish CBC mode encrypted TLS session. Repeated sending of communication protocol with parts of the plaintext helps attackers to reconstruct the secret information.

Successful exploitation of this vulnerability may allow a remote attacker to access potentially sensitive data.

Mitigation

Install update from vendor's website.
