| Title: | RHSA-2008:0815: yum-rhn-plugin security update (Moderate) |
| Description: | The yum-rhn-plugin provides support for yum to securely access a Red Hat Network (RHN) server for software updates.
It was discovered that yum-rhn-plugin did not verify the SSL certificate for all communication with a Red Hat Network server. An attacker able to redirect the network communication between a victim and an RHN server could use this flaw to provide malicious repository metadata. This metadata could be used to block the victim from receiving specific security updates. (CVE-2008-3270)
This flaw did not allow an attacker to install malicious packages. Package signatures were verified and only packages signed with a trusted Red Hat GPG key were installed.
Red Hat would like to thank Justin Cappos and Justin Samuel for discussing various package update mechanism flaws which led to our discovery of this issue.
Users of yum-rhn-plugin are advised to upgrade to this updated packages, which resolves this issue.
