Vulnerability Name:

CVE-2017-7652 (CCN-142397)

Assigned:2017-04-11
Published:2018-04-25
Updated:2019-10-09
Summary:In Eclipse Mosquitto 1.4.14, if a Mosquitto instance is set running with a configuration file, then sending a HUP signal to server triggers the configuration to be reloaded from disk. If there are lots of clients connected so that there are no more file descriptors/sockets available (default limit typically 1024 file descriptors on Linux), then opening the configuration file will fail.
