[$] Remote execution in the GNOME tracker

While the vulnerability itself is pretty run-of-the-mill, the recently disclosedGNOME vulnerability has a number of interesting facets. The problem liesin a library that reads files in a fairly obscure format, but it turns outthat files in that format are routinely-automatically-processed by GNOME ifthey are downloaded to the local system. That turns a vulnerability in alargely unknown library into a one-click remote-code-execution flaw forthe GNOME desktop.
