Description Josh Bressers 2007-02-19 20:37:42 UTC

+++ 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 gnomemeeting

This flaw also affects RHEL3

Comment 1 Josh Bressers 2007-02-19 20:44:22 UTC

<mjcox> well a case of replacing   gnomemeeting_log_insert (msg); with  
gnomemeeting_log_insert ("%s",msg); etc

Comment 3 Mark J. Cox 2007-02-20 08:56:09 UTC

I think it's important to note that the format string flaws in Ekiga are not the
same as the format string flaws in Gnomemeeting, although they are of a similar
root cause..  In Ekiga this occurs because the remote name is passed to a
display function as a format string, in GnomeMeeting because the remote name is
passed to a logging function as a format string.  Therefore there are two CVE
names even though the way to trigger these flaws is the same (connect with a
malicious name).
