Vulnerability from fkie_nvd - Published: 2013-09-30 21:55 - Updated: 2026-06-16 23:57
Severity
Summary
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.
