Description Jan Lieskovsky 2009-02-21 05:43:34 EST
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-0654 to
the following vulnerability:

Tor, and probably and earlier, allows remote
attackers, with control of an entry router and an exit router, to
confirm that a sender and receiver are communicating via vectors
involving (1) replaying, (2) modifying, (3) inserting, or (4) deleting
a single cell, and then observing cell recognition errors at the exit
router. NOTE: the vendor disputes the significance of this issue,
noting that the product's design "accepted end-to-end correlation as
an attack that is too expensive to solve."

Comment 1 Vincent Danen 2011-01-20 16:46:27 EST
We do not have any supported products with tor 0.2.0.x, so closing this.
