I can't find any information about this. What I did find in Books Online
was that if you run the Rebuild Master utility, you will need to restore
msdb, as this utility writes a new msdb.

DBCC with various repair options may be an alternative, but I would
certainly prefer a backup if there is one recent.

Just restore. But you will have to make sure that SQL Agent is not
running. You may find http://www.dbarecovery.com/restoremsdb.html
