.. _`#1438`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1438
+** Security-related Bugfix
+
+ - Fix flaw that would allow a person who knows a storage index of a file to
+ delete shares of that file (#1528).
+ - Remove corner cases in mutable file bounds management which could expose
+ extra lease info or old share data (from prior versions of the mutable
+ file) if someone with write authority to that mutable file exercised these
+ corner cases in a way that no actual Tahoe-LAFS client does. (Probably not
+ exploitable.) (#1528).
