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.
