Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) State Issues

EUVDB-ID: #VU73829

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-27536

CWE-ID: CWE-371 - State Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to cURL will reuse a previously created connection even when the GSS delegation (CURLOPT_GSSAPI_DELEGATION) option had been changed that could have changed the user's permissions in a second transfer. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, this GSS delegation setting was left out from the configuration match checks, making them match too easily, affecting krb5/kerberos/negotiate/GSSAPI transfers.

Mitigation

Install update from vendor's website.

2) Improper certificate validation

EUVDB-ID: #VU76237

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-2023-28321

CWE-ID: CWE-295 - Improper Certificate Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to improper certificate validation when matching wildcards in TLS certificates for IDN names. A remote attacker crate a specially crafted certificate that will be considered trusted by the library.

Successful exploitation of the vulnerability requires that curl is built to use OpenSSL, Schannel or Gskit.
