More information:

It was discovered that Tor, a connection-based low-latency anonymous communication system, may read one byte past a buffer when parsing hidden service descriptors. This issue may enable a hostile hidden service to crash Tor clients depending on hardening options and malloc implementation.

For Debian 7 Wheezy, these problems have been fixed in version 0.2.4.27-3.

We recommend that you upgrade your tor packages.
