Updated curl packages are now available. This update has been rated as having low security impact by the CentOS Security Response Team.
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 CAN-2005-0490 to this issue. All users of curl are advised to upgrade to these updated packages, which contain backported fixes for these issues.
