For long messages, it'll trigger as many read(2) calls as the length of a message. Thus consuming extra CPU cycles. A malicious remote user could use this to cause a DoS. Upstream fix: ------------- -> https://github.com/pjps/ndjbdns/commit/a67293ce12832b55ec4271536282290ed17863f6 Reference: ---------- -> http://download.pureftpd.org/misc/dnscache-dos.c Thank you. -- Prasad J Pandit / Red Hat Security Response Team
