This update fixes this upgrade scenario.

For reference, the original advisory text follows.

Multiple vulnerabilities were discovered in python2.6. The more relevant are:

CVE-2013-4238

Incorrect handling of NUL bytes in certificate hostnames may allow server spoofing via specially-crafted certificates signed by a trusted Certification Authority.

CVE-2014-1912

Buffer overflow in socket.recvfrom_into leading to application crash and possibly code execution.

For Debian 6 Squeeze, these issues have been fixed in python2.6 version 2.6.6-8+deb6u2");
