CVE-2023-22551
The FTP (aka "Implementation of a simple FTP client and server") project through 96c1a35 allows remote attackers to cause a denial of service (memory consumption) by engaging in client activity, such as establishing and then terminating a connection.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The FTP (aka "Implementation of a simple FTP client and server") project through 96c1a35 allows remote attackers to cause a denial of service (memory consumption) by engaging in client activity, such as establishing and then terminating a connection. This occurs because malloc is used but free is not.
