CVE-2012-1014: Mit Kerberos 5

High severity, CVSS 9.0. EPSS: 4.3% chance of exploitation in the next 30 days.

The process_as_req function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.10.x before 1.10.3 does not initialize a certain structure member, which allows remote attackers to cause a denial of service (uninitialized pointer dereference and daemon crash) or possibly execute arbitrary code via a malformed AS-REQ request.

Affected products

• Mit Kerberos 5: version 1.10 only; version 1.10.1 only; version 1.10.2 only
