curl -- TFTP packet buffer overflow vulnerability

A Project cURL Security Advisory reports:

libcurl uses the given file part of a TFTP URL in a manner that
allows a malicious user to overflow a heap-based memory buffer due
to the lack of boundary check.
This overflow happens if you pass in a URL with a TFTP
protocol prefix (“tftp://”), using a valid host and a path
part that is longer than 512 bytes.
The affected flaw can be triggered by a redirect, if
curl/libcurl is told to follow redirects and an HTTP
server points the client to a tftp URL with the
characteristics described above.
