3. Description:

cURL provides the libcurl library and a command line tool for downloading
files from servers using various protocols, including HTTP, FTP, and LDAP.

It was found that cURL always performed credential delegation when
authenticating with GSSAPI. A rogue server could use this flaw to obtain
the client's credentials and impersonate that client to other servers that
are using GSSAPI. (CVE-2011-2192)

Users of curl should upgrade to these updated packages, which contain a
backported patch to correct this issue. All running applications using
libcurl must be restarted for the update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
