Amazon Linux AMI : python26 (ALAS-2013-241)

medium Nessus Plugin ID 70903

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

It was discovered that multiple Python standard library modules implementing network protocols (such as httplib or smtplib) failed to restrict sizes of server responses. A malicious server could cause a client using one of the affected modules to consume an excessive amount of memory. (CVE-2013-1752)

The ssl.match_hostname function in the SSL module in Python 2.6 through 3.4 does not properly handle a '\0' character in a domain name in the Subject Alternative Name 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-2013-4238)

Solution

Run 'yum update python26' to update your system.
