1) Input validation error

EUVDB-ID: #VU87672

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-28835

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input when parsing the cert_list_size parameter in the gnutls_x509_trust_list_verify_crt2() function in certtool. A remote attacker can pass specially crafted PEM encoded certificate chain that contains more than 16 certificates to the certtool and crash it.

Mitigation

Install updates from vendor's repository.
