Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU63008

Risk: Medium

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

CVE-ID: CVE-2022-27781

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

Exploit availability: No

Description

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

The vulnerability exists due to infinite loop when handling requests with the CURLOPT_CERTINFO option. A remote attacker can consume all available system resources and cause denial of service conditions.

Mitigation

Update the affected package curl to the latest version.

2) Incorrect Implementation of Authentication Algorithm

EUVDB-ID: #VU63009

Risk: Medium

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:Green]

CVE-ID: CVE-2022-27782

CWE-ID: CWE-303 - Incorrect Implementation of Authentication Algorithm

Exploit availability: No

Description

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

The vulnerability exists due to the way libcurl handles previously used connections in a connection pool for subsequent transfers. Several TLS and SSH settings were left out from the configuration match checks, resulting in erroneous matches for different resources. As a result, libcurl can send authentication string from one resource to another, exposing credentials to a third-party.

Mitigation

Update the affected package curl to the latest version.
