execution of arbitrary code.

libxml2 is an XML parsing library written in C.
Multiple buffer overflows have been detected in the nanoftp and nanohttp
modules. These modules are responsible for parsing URLs with ftp
information, and resolving names via DNS.
<impact type="high">
An attacker could exploit an application that uses libxml2 by forcing it to
parse a specially-crafted XML file, potentially causing remote execution of
arbitrary code.
There is no known workaround at this time.
All libxml2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.6.15"</code>
