Fedora Update Notification
FEDORA-2011-8943
2011-07-01 18:25:51
--------------------------------------------------------------------------------

Name        : PackageKit
Product     : Fedora 15
Version     : 0.6.15
Release     : 2.fc15
URL         : http://www.packagekit.org
Summary     : Package management service
Description :
PackageKit is a D-Bus abstraction layer that allows the session user
to manage packages in a secure way using a cross-distro,
cross-architecture API.

--------------------------------------------------------------------------------
Update Information:

- Upstream yum recently changed the behaviour when checking signatures on a
package. The commit added a new configuration key which only affects local
packages, but the key was set by default to False.
- This meant that an end user could install a local unsigned rpm package using
PackageKit without a GPG trust check, and the user would be told the untrusted
package is itself trusted.
- To exploit this low-impact vulnerability, a user would have to manually
download an unsigned package file and would still be required to authenticate to
install the package.
- The CVE-ID for this bug is CVE-2011-2515
- See https://bugzilla.redhat.com/show_bug.cgi?id=717566 for details.
