Secure testing team - Dec 2009 - Bug#560067: network-manager-gnome: nm connects to WPA2 with certificate after .pem file was delated

Package: network-manager-gnome
Version: 0.7.2-1
Severity: grave
Tags: security
Justification: user security hole

After configuring WPA2 Enterprise with TTLS and PAP, I was using certificate
file
in /etc/ssl/certs/...pem  (autmatically imported from
/usr/local/share/ca-certificates/domain/certrootfile.crt)


Then i reinstalled system, and not configured certifcates yet.

After reinstalling system and restoring /home directory, i logged into my new
stystem.

After giving password to gnome-keyring NM automatically connected to my network,
even cosindering that it is not existing:

** (nm-applet:6704): WARNING **: utils_fill_connection_certs: couldn''t
read CA certificate: 4 Nie mo?na otworzy? pliku
"/etc/ssl/certs/SMP_Root_Certification_Authority_2.pem": Nie ma
takiego pliku ani katalogu



But NM thinks that it should connect anyway. And it connects,
possibly leaking my credentials, login and password, and all
keys, and of course network traffic.


It should be considerebly more verbose error provided to an user (using
nm-applet),
and NM should abort connecting.
