cURL is a tool for getting files from FTP, HTTP, Gopher, Telnet, and
Dict servers, using any of the supported protocols. cURL is designed
to work without user interaction or any kind of interactivity.

Multiple buffer overflow bugs were found in the way curl processes
base64 encoded replies. If a victim can be tricked into visiting a URL
with curl, a malicious web server could execute arbitrary code on a
victim's machine. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2005-0490 to this issue.

All users of curl are advised to upgrade to these updated packages,
which contain backported fixes for these issues."
