Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU61391

Risk: Medium

CVSSv3.1:

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.
