_______________________________________________________________________

Package : libneon0.27
Date : August 24, 2009
Affected: 2008.1, 2009.0, 2009.1, Corporate 4.0, Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in libneon0.27:

neon before 0.28.6, when expat is used, does not properly detect
recursion during entity expansion, which allows context-dependent
attackers to cause a denial of service (memory and CPU consumption)
via a crafted XML document containing a large number of nested entity
references, a similar issue to CVE-2003-1564 (CVE-2009-2473).

neon before 0.28.6, when OpenSSL is used, does not properly handle a
'\0' (NUL) character in a domain name in the subject's Common Name
(CN) field of an X.509 certificate, which allows man-in-the-middle
attackers to spoof arbitrary SSL servers via a crafted certificate
issued by a legitimate Certification Authority, a related issue to
CVE-2009-2408 (CVE-2009-2474).

This update provides a solution to these vulnerabilities.
