DESCRIPTION:
A vulnerability has been reported in Tahoe-LAFS, which can be
exploited by malicious people to manipulate certain data.
The vulnerability is caused due to Tahoe-LAFS not properly preventing
clients from reading past the end of share data, which can be used to
gain knowledge of the cancellation secret. This can be exploited to
delete shares from the server by e.g. calling the
"remote_cancel_lease()" function.
The vulnerability is reported in versions 1.3.0 through 1.8.2.
SOLUTION:
Update to version 1.8.3.
PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
