Bug#692442: CVE-2012-5783: Insecure certificate validation

[Moritz Muehlenhoff]

Package: commons-httpclient
Severity: important
Tags: security

Please see Section 7.5 of this paper:
http://www.cs.utexas.edu/~shmat/shmat_ccs12.pdf

This has been assigned CVE-2012-5783. I'm not sure if we can backport more
correct certificate validation to 3.x, but independent of that it might
make sense to introduce the 4.x codebase to the archive?

Cheers,
