Debian DLA-1334-1 : mosquitto security update

high Nessus Plugin ID 108768

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2017-7651 A crafted CONNECT packet from an unauthenticated client could result in extraordinary memory consumption.

CVE-2017-7652 In case all sockets/file descriptors are exhausted, a SIGHUP signal to reload the configuration could result in default config values (especially bad security settings)

For Debian 7 'Wheezy', these problems have been fixed in version 0.15-2+deb7u3.

We recommend that you upgrade your mosquitto packages.

Solution

Upgrade the affected packages.
