- 漏洞描述

SurgeFTP contains a flaw that may allow a remote denial of service. The issue is triggered when receiving the LEAK command, SurgeFTP will call the cmd_leak() function. cmd_leak() will in turn call the mgr_cmd_openmore() function. mgr_cmd_openmore() will open the file "a.a_write" 925 times, thus potentially causing the process to run out of file handles, and will result in loss of availability for the server.
