Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2024-28835)
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.
