Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos.
Versions prior to 7.7.1 are vulnerable to a denial of service
vulnerability in Heimdal's PKI certificate validation library,
affecting the KDC (via PKINIT) and kinit (via PKINIT), as well as
any third-party applications using Heimdal's libhx509. Users
should upgrade to Heimdal 7.7.1 or 7.8. There are no known
workarounds for this issue.

+Subject: [PATCH] lib/wind: find_normalize read past end of array
+
+find_normalize() can under some circumstances read one element
+beyond the input array.  The contents are discarded immediately
+without further use.
+
+This change prevents the unintended read.
+
+(cherry picked from commit 357a38fc7fb582ae73f4b7f4a90a4b0b871b149e)
