FreeBSD : asterisk -- Buffer overflow in CDR's set user (356b02e9-1954-11e7-9608-001999f8d30b)

high Nessus Plugin ID 99192

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The Asterisk project reports :

No size checking is done when setting the user field on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. This allows the possibility of remote code injection.

Solution

Update the affected package.
