Description Mark J. Cox 2005-10-10 09:23:12 UTC 
Note that FORTIFY_SOURCE as lynx is compiled with in FC4, does not block this
vulnerability.  Also affects FC3.  See bz#170253 for proposed patch.

+++ This bug was initially created as a clone of Bug #170253 +++

Ulf Harnhammar found a flaw in Lynx that can be triggered when Lynx connects to
a NNTP server.  A malicious news server could cause a buffer overflow, leading
to the potential of arbitrary code execution as the user running lynx.  This
issue requires a victim connects to the malicious news server, however this
could be forced by a redirect from any malicious web page.

Embargo set for 20051017
