high Nessus Plugin ID 65043


The remote Scientific Linux host is missing one or more security updates.


CVE-2009-2417 curl: incorrect verification of SSL certificate with NUL in name

Scott Cantor reported that cURL is affected by the previously published 'null prefix attack', caused by incorrect handling of NULL characters in X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse cURL into accepting it by mistake. (CVE-2009-2417)

All running applications using libcurl must be restarted for the update to take effect.

Note: This package for SL4 has to be renamed due to poor naming of rpms.


Update the affected curl and / or curl-devel packages.
