Summary: An updated yum-updatesd package that fixes one security issue is now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - noarch Red Hat Enterprise Linux Desktop (v. 5 client) - noarch 3. Description: The yum-updatesd package provides a daemon which checks for available updates and can notify you when they are available via email, syslog, or dbus. It was discovered that yum-updatesd did not properly perform RPM package signature checks. When yum-updatesd was configured to automatically install updates, a remote attacker could use this flaw to install a malicious update on the target system using an unsigned RPM or an RPM signed with an untrusted key. (CVE-2014-0022) All yum-updatesd users are advised to upgrade to this updated package, which contains a backported patch to correct this issue. After installing this update, the yum-updatesd service will be restarted automatically. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 5.
