[Bug crypt/22781] New: Cache Side Channel in /sunrpc/des_impl.c


https://sourceware.org/bugzilla/show_bug.cgi?id=22781

            Bug ID: 22781
           Summary: Cache Side Channel in /sunrpc/des_impl.c
           Product: glibc
           Version: 2.26
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: crypt
          Assignee: unassigned at sourceware dot org
          Reporter: rbrot249 at gmail dot com
  Target Milestone: ---

The DES implementation in this file does not do any preloading  or some other
defense (as far as I can see) to prevent someone from observing cache
hits/misses caused by key dependent memory accesses to the precomputed tables.
