(RHSA-2011:0918) Moderate: curl security update

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.
