Alpine: multiple heimdal packages: security update to 7.1.0-r1 (deprecated)

high Tenable Self-Hosted Container Security Plugin ID 400857

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)
