DESCRIPTION:
A security issue has been reported in Tahoe-LAFS, which can be
exploited by malicious people to manipulate certain data.
The security issue is caused due to a logic error within the
integrity checking of the mutable downloader, which can be exploited
to deliver manipulated shares to a client without triggering an
integrity failure.
Successful exploitation requires that the attacker is able to provide
multiple shares in a certain order to a client (e.g. controls one or
more storage servers).
The security issue is reported in version 1.9.0.
SOLUTION:
Update to version 1.9.1.
