Description

This update includes the latest release of neon, version 0.28.6. This fixes two security issues: * the 'billion laughs' attack against expat could allow a Denial of Service attack by a malicious server. (CVE-2009-2473) * an embedded NUL byte in a certificate subject name could allow an undetected MITM attack against an SSL server if a trusted CA issues such a cert.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
