Red Hat Security Advisory
Synopsis: Moderate: neon security update
Advisory ID: RHSA-2009:1452-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1452.html
Issue date: 2009-09-21
CVE Names: CVE-2009-2473 CVE-2009-2474
=====================================================================
1. Summary:
Updated neon packages that fix two security issues are now available for
Red Hat Enterprise Linux 4 and 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
3. Description:
neon is an HTTP and WebDAV client library, with a C interface. It provides
a high-level interface to HTTP and WebDAV methods along with a low-level
interface for HTTP request handling. neon supports persistent connections,
proxy servers, basic, digest and Kerberos authentication, and has complete
SSL support.
It was discovered that neon 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 an
application using the neon library into accepting it by mistake.
(CVE-2009-2474)
A denial of service flaw was found in the neon Extensible Markup Language
(XML) parser. A remote attacker (malicious DAV server) could provide a
specially-crafted XML document that would cause excessive memory and CPU
consumption if an application using the neon XML parser was tricked into
processing it. (CVE-2009-2473)
All neon users should upgrade to these updated packages, which contain
backported patches to correct these issues. Applications using the neon
HTTP and WebDAV client library, such as cadaver, must be restarted for this
update to take effect.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
518215 - CVE-2009-2473 neon, gnome-vfs2 embedded neon: billion laughs DoS attack
518223 - CVE-2009-2474 neon: Improper verification of x509v3 certificate with NULL (zero) byte in certain fields
