cURL is a tool for getting files from FTP, HTTP, Gopher, Telnet, and Dictservers, using any of the supported protocols. cURL is designed to workwithout user interaction or any kind of interactivity.David Kierznowski discovered a flaw in libcurl where it would notdifferentiate between different target URLs when handling automaticredirects. This caused libcurl to follow any new URL that it understood,including the "file://" URL type. This could allow a remote server to forcea local libcurl-using application to read a local file instead of theremote one, possibly exposing local files that were not meant to beexposed. (CVE-2009-0037)Note: Applications using libcurl that are expected to follow redirects to"file://" protocol must now explicitly call curl_easy_setopt(3) and set thenewly introduced CURLOPT_REDIR_PROTOCOLS option as required.cURL users should upgrade to these updated packages, which containbackported patches to correct these issues. All running applications usinglibcurl must be restarted for the update to take effect.
