Debian DLA-1525-1 : mosquitto security update
Medium Nessus Plugin ID 117835
SynopsisThe remote Debian host is missing a security update.
As invalid UTF-8 strings are not correctly checked, an attacker could cause a denial of service to other clients by disconnecting them from the broker with special crafted topics.
Due to a memory leak unauthenticated clients can send special crafted CONNECT packets which could cause a denial of service in the broker.
Due to wrong file permissions local users could obtain topic information from the mosquitto database.
For Debian 8 'Jessie', these problems have been fixed in version 1.3.4-2+deb8u3.
We recommend that you upgrade your mosquitto packages.
