SERVER-OTHER ZeroMQ libzmq stack-based buffer overflow attempt
This event is generated when an attempt to exploit CVE-2019-13132 is detected.
Attempted User Privilege Gain
A stack-based buffer overflow exists in ZeroMQ libzmq due to improper validation of the 'INITIATE' command in 'curve_server.cpp'. A remote, unauthenticated attacker could exploit this vulnerability by sending a specially crafted packet to the vulnerable service. Successful exploitation could result in denial of service conditions, or execution of arbitrary code.
