CentOS 3 / 4 : curl (CESA-2009:0341)

Medium Nessus Plugin ID 35965


The remote CentOS host is missing one or more security updates.


Updated curl packages that fix a security issue are now available for Red Hat Enterprise Linux 2.1, 3, 4, and 5.

This update has been rated as having moderate security impact by the Red Hat 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.

David Kierznowski discovered a flaw in libcurl where it would not differentiate between different target URLs when handling automatic redirects. This caused libcurl to follow any new URL that it understood, including the 'file://' URL type. This could allow a remote server to force a local libcurl-using application to read a local file instead of the remote one, possibly exposing local files that were not meant to be exposed. (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 the newly introduced CURLOPT_REDIR_PROTOCOLS option as required.

cURL users should upgrade to these updated packages, which contain backported patches to correct these issues. All running applications using libcurl must be restarted for the update to take effect.


Update the affected curl packages.
