Summary
- -------------------------------------------------------------------- GENTOO LINUX SECURITY ANNOUNCEMENT 200301-2 - -------------------------------------------------------------------- DATE : 2003-01-02 11:01 UTC
- --------------------------------------------------------------------
From leafnode advisory:
"This vulnerability can make leafnode's nntpd server, named leafnode, go into an unterminated loop when a particular article is requested. The connection becomes irresponsive, and the server hogs the CPU. The client will have to terminate the connection and connect again, and may fall prey to the same problem; ultimately, there may be so many leafnode processes hogging the CPU that no serious work is possible any more and the super user has to kill all running leafnode processes."

emerge rsync emerge leafnode emerge clean
