CVE-2015-2696: Canonical Ubuntu Linux

High severity, CVSS 7.1. EPSS: 4.5% chance of exploitation in the next 30 days.

lib/gssapi/krb5/iakerb.c in MIT Kerberos 5 (aka krb5) before 1.14 relies on an inappropriate context handle, which allows remote attackers to cause a denial of service (incorrect pointer read and process crash) via a crafted IAKERB packet that is mishandled during a gss_inquire_context call.
