"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."
