The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-3088 to this issue. Users of fetchmail are advised to upgrade to these updated packages, which contain a backported patch which resolves this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network.
