Alpine: multiple heimdal packages: security update to 7.8.0-r2

high Tenable Cloud Security Plugin ID 423996

Description

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

 - The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug
 by adding "!= 0" comparisons to the result of memcmp. When these patches were backported to the
 heimdal-7.7.1 and heimdal-7.8.0 branches (and possibly other branches) a logic inversion sneaked in
 causing the validation of message integrity codes in gssapi/arcfour to be inverted. (CVE-2022-45142)
