Mandriva Linux Security Advisory : libneon0.27 (MDVSA-2009:221)

Medium Nessus Plugin ID 40764


The remote Mandriva Linux host is missing one or more security updates.


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 '�' (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.


Update the affected packages.
