cURL -- potential memory disclosure

The cURL project reports:

There were two bugs in curl’s parser for the command line option
–write-out (or -w for short) that would skip the end of string
zero byte if the string ended in a % (percent) or \ (backslash),
and it would read beyond that buffer in the heap memory and it
could then potentially output pieces of that memory to the
terminal or the target file etc…
This flaw only exists in the command line tool.
We are not aware of any exploit of this flaw.
