RHEL 3 / 4 / 5 : curl (RHSA-2009:1209)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated curl packages that fix security issues are now available for
Red Hat Enterprise Linux 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.

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)

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