CVE-2009-0846 is a critical vulnerability in the ASN.1 GeneralizedTime decoder within MIT Kerberos 5 (krb5) versions prior to 1.6.4, affecting products from vendors like Apple, Canonical, Fedora Project, MIT, and Red Hat. This flaw allows remote, unauthenticated attackers to cause a denial of service (daemon crash) or potentially execute arbitrary code by sending a specially crafted, invalid DER encoding that triggers a free of an uninitialized pointer. With a CVSS score of 10.0 and a FAUCET Risk Score of 98/100, its severity is extremely high due to the network-based attack vector, low attack complexity, and complete impact on confidentiality, integrity, and availability. Despite its age and high severity, there is no known active exploitation, publicly available exploit code in Metasploit or ExploitDB, nor significant community discussion or media coverage.
