Could someone help me with a Shell Script OR a perl script which could read the below INPUT File and print output in format listed below.

The logic I am looking for is to read each block within the asterisk line, then search for "until:". If the date of "until:" is less than OR equal to current date, then print the "Alias Name".

START OF INPUT FILE (NOTE INPUT FILE IS IN BELOW FORMAT INCLUDING ASTERISKS LINES)

For a (ba)sh script I'd look at (g)awk, which allows you to write little functions based on a regex match. You can set (global) variables within the functions, and you can check their values which gives you something resembling a state machine.
