There are two distinct buffer overflows:
* Off-by-one heap overflow when parsing addresses that have left angle
bracket, then a comma, but no right angle bracket. For example:
<moo@...mple.com,
* Heap overflow when parsing addresses that end with backslash. For
example: <moo@...mple.com\
Credit goes to Jan Darmochwal for identifying the root causes.
