CVE-2013-4359
Integer overflow in kbdint.c in mod_sftp in ProFTPD 1.3.4d and 1.3.5r3 allows remote attackers to cause a denial of service (memory consumption) via a large response count value in an authentication request, which triggers a large memory allocation.

Does this matter?
Lower severity and a low EPSS score (2.99%). Track it; it rarely justifies an emergency change on its own.
