Description of problem:
prozilla 1.3.7.3 has a remotely exploitable buffer overflow, as described in <http://www.securiteam.com/exploits/5WP082KEUW.html>. This is due to overflows of fixed-sized buffers in the HTTP redirection code.

This is fixed in prozilla 1.3.7.4. Changes in 1.3.7.4, from its NEWS file:

"* Support for downloading files > 2GB.

* Fix a remotely exploitable format string security bug.

* Fix bugs in the handling of bad command-line options. Previously
  prozilla would return the success status code, even though it failed.
  Now it returns failure.

* Fix a segfault. This occurred when prozilla could not assemble a file
  due to lack of disk space and the user chose to abort the operation.

* Fix some typos."

Version-Release number of selected component (if applicable):
prozilla-1.3.7.3-2

How reproducible:
Sometimes

Steps to Reproduce:
1. Create a special account for running the test. I called this account "victim". prozilla will be run from this and will be exploited.
2. Build and run the exploit code from the Securiteam advisory. This runs a fake web server.
3. Connect to the fake webserver.
4. See prozilla has been exploited.

Actual Results:  Worked on FC3 on i386. Didn't seem to work on FC3 on x86_64, but that may just have been lucky.
