Description

CVE-2009-2473 neon, gnome-vfs2 embedded neon: billion laughs DoS attack

CVE-2009-2474 neon: Improper verification of x509v3 certificate with NULL (zero) byte in certain fields

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)

Applications using the neon HTTP and WebDAV client library, such as cadaver, must be restarted for this update to take effect.

Solution

Update the affected neon and / or neon-devel packages.
