CVE-2011-1179 spice-xpi: unitialized pointer writes possible when getting plugin properties
An uninitialized pointer use flaw was found in the SPICE Firefox plug-in. If a user were tricked into visiting a malicious web page with Firefox while the SPICE plug-in is enabled, it could cause Firefox to crash or, possibly, execute arbitrary code with the privileges of the user running Firefox.

The specifics of the CVEs are as follows:
* Name: CVE-2011-0015
* Reference: https://trac.torproject.org/projects/tor/ticket/2324
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not
properly check the amount of compression in zlib-compressed data,
which allows remote attackers to cause a denial of service via a large
compression factor.
* Name: CVE-2011-0016
* Reference: https://trac.torproject.org/projects/tor/ticket/2384
