Hi MITRE team,

The Debian bug report does not contain diagnosis of the type of
programming error that is triggering each crash, so it is not clear how
many CVE identifiers must be assigned.

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 () example com,

* Heap overflow when parsing addresses that end with backslash. For example:
<moo () example com\

Credit goes to Jan Darmochwal for identifying the root causes.

Not sure if this got lost, so just reasking. Can you assing CVEs based
on the above? (actually one or two CVEs?)

Regards,
Salvatore
