"Updated curl packages that fix one security issue are now available
for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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."
