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.
