Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Guido Vranken reports :

HTTP header injection in urrlib2/urllib/httplib/http.client with newlines in header values, where newlines have a semantic consequence of denoting the start of an additional header line.

Solution
