CVE-2013-4359 medium priority: Ubuntu including 1 source packages (proftpd-dfsg), 15 status rows across 15 suites (artful, bionic, lucid, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): not-affected 8, ignored 5, DNE 1, released 1.
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.
