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.

A heap-based buffer overflow flaw was found in the way libcurl unescaped
URLs. A remote attacker could provide a specially-crafted URL that, when
processed by an application using libcurl that handles untrusted URLs,
would possibly cause it to crash or, potentially, execute arbitrary code.
(CVE-2013-2174)

Red Hat would like to thank the cURL project for reporting this issue.
Upstream acknowledges Timo Sirainen as the original reporter.

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/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):
