FreeBSD : asterisk -- Buffer overflow in CDR's set user (ab04cb0b-c533-11e7-8da5-001999f8d30b)

high Nessus Plugin ID 104490

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 for Party B 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. The earlier AST-2017-001 advisory for the CDR user field overflow was for the Party A buffer.

Solution

Update the affected package.
