network-manager-applet vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 9.04
  • Ubuntu 8.10

Software description

  • network-manager-applet


It was discovered that NetworkManager did not ensure that the Certification
Authority (CA) certificate file remained present when using WPA Enterprise
or 802.1x networks. A remote attacker could use this flaw to spoof the
identity of a wireless network and view sensitive information.

It was discovered that the connection editor GUI would incorrectly export
objects over D-Bus. A local user could read D-Bus signals to view other
users' network connection passwords and pre-shared keys. (CVE-2009-4145)
