Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for neon.

CVE-2009-2474[0]:
neon before 0.28.6, when OpenSSL is used, does not properly handle a
'\0' 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.


If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
