Alpine: samba: security update to 4.4.14-r1

high Tenable Self-Hosted Container Security Plugin ID 407095

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it
 obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In
 _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in
 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides
 an opportunity for successful server impersonation and other attacks. NOTE: this CVE is only for Heimdal
 and other products that embed Heimdal code; it does not apply to other instances in which this part of the
 Kerberos 5 protocol specification is violated. (CVE-2017-11103)
