3. Problem description:

cURL is a tool for getting files from FTP, HTTP, Gopher, Telnet, and Dict
servers, using any of the supported protocols.

Stefan Esser discovered an off-by-one bug in curl. It may be possible to
execute arbitrary code on a user's machine if the user can be tricked into
executing curl with a carefully crafted URL. The Common Vulnerabilities and
Exposures project assigned the name CVE-2005-4077 to this issue. 

All users of curl are advised to upgrade to these updated packages, which
contain a backported patch that 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.  To use Red Hat Network,

RPMs being upgraded on your system.
