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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
