Title:	Amazon Linux: Security Advisory (ALAS-2015-624)
Summary:	The remote host is missing an update for the 'krb5' package(s) announced via the ALAS-2015-624 advisory.
Description:	Summary: The remote host is missing an update for the 'krb5' package(s) announced via the ALAS-2015-624 advisory. Vulnerability Insight: A flaw was found in the OTP kdcpreauth module of MIT Kerberos. A remote attacker could use this flaw to bypass the requires_preauth flag on a client principal and obtain a ciphertext encrypted in the principal's long-term key. This ciphertext could be used to conduct an off-line dictionary attack against the user's password. It was found that the krb5_read_message() function of MIT Kerberos did not correctly sanitize input, and could create invalid krb5_data objects. A remote, unauthenticated attacker could use this flaw to crash a Kerberos child process via a specially crafted request. Affected Software/OS: 'krb5' package(s) on Amazon Linux. Solution: Please install the updated package(s). CVSS Score: 5.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:N
