Description Josh Bressers 2007-02-19 15:13:04 EST
+++ This bug was initially created as a clone of Bug #229259 +++

A format string flaw was found in the way Ekiga processes certain messages form
remote clients.  This flaw could allow a remote attacker to execute arbitrary
code as the user running Ekiga.

This flaw also affects FC5

They are building now, task  

   http://brewweb.devel.redhat.com/brew/taskinfo?taskID=637346

I wasn't sure whether these would go into -qu-candiate or -candiate, so I took a
guess.
Comment 6 Mark J. Cox (Product Security) 2007-03-05 11:34:00 EST
failed qa as there is a double vsnprintf which strips the first %s.  Looks like
a bug.  Possible fix:

New packages that will hopefully fix - see ekiga-2_0_2-7_0_1
Comment 8 Mark J. Cox (Product Security) 2007-03-07 04:35:46 EST
Failed qa due to a double vsnprintf which opened up the format string flaws; so
CVE-2007-0999 for the new format string flaws.
