CVE-2017-7652 (GCVE-0-2017-7652)

Vulnerability from cvelistv5 – Published: 2018-04-25 13:00 – Updated: 2024-08-05 16:12

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.

Severity

No CVSS data available.

CWE

CWE-789 - Uncontrolled Memory Allocation
