Anonymizer Guards Against Evercookie JavaScript API With Free Firefox Plugin

Plug-in extends Firefox's private browsing mode

SAN DIEGO, Nov. 10, 2010 /PRNewswire/ -- Anonymizer, Inc., www.anonymizer.com, the leader in consumer online anonymity solutions, announced today that it has developed Anonymizer Nevercookie, a free Firefox plugin that protects against the Evercookie API. The plugin extends Firefox's private browsing mode by preventing Evercookies from identifying and tracking users. Anonymizer Nevercookie will be available as a free download later this month.

"Recent developments in Web tracking technologies have rendered the privacy tools built into browsers almost completely ineffective," said Lance Cottrell, founder and chief scientist for Anonymizer. "Anonymizer Nevercookie will close the gap between Firefox's privacy features and actual privacy so that when you go into private browsing mode, you are truly protected."

Evercookie is a new, more persistent cookie form that enables the storage of cookie data in a number of different locations, such as Flash cookies and various locations of HTML5 storage. This allows websites to track user behavior even when users have enabled private browsing. Because an Evercookie stores data in locations outside of where standard cookies are stored, an Evercookie can rebuild itself unless users go through a number of steps to completely clear and reset their local storage.

Anonymizer Nevercookiesimplifies this process and eliminates the manual steps required to completely remove Evercookies. And it does so without also removing all of the necessary cookies that a user actually wants to keep, such as those for browsing history and remembered logins. When Anonymizer Nevercookie is engaged along with Firefox's private browsing mode, it quarantines an Evercookie and removes it after the browsing session.

Dr. Elie Burzstein, a noted Web security researcher at the Stanford University Research Lab, stated: "My testing and review found that when using Anonymizer Nevercookie along with Firefox's private browsing mode, users are protected from all of the currently known tracking systems that use browser features to follow users across multiple sessions, such as Evercookie. Specifically, Nevercookie prevents abuse to both the Adobe Flash Local Storage Object (LSO) and Microsoft's Silverlight Isolated Storage (MIS)."

Anonymizer Nevercookie was developed by Anonymizer Labs, a dedicated research and development division of Anonymizer, Inc.

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...
CVE-2020-15211
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...
CVE-2020-15212
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
