high Nessus Plugin ID 104487

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

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.

Solution

Update the affected packages.
