Description

The Asterisk project reports:

By carefully crafting invalid values in the Cseq and

the Via header port, pjprojects packet parsing code can

create strings larger than the buffer allocated to hold

them. This will usually cause Asterisk to crash immediately.

The packets do not have to be authenticated.
