Amazon Linux AMI : python26 (ALAS-2015-621)

critical Nessus Plugin ID 87347
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

An integer overflow flaw was found in the way the buffer() function handled its offset and size arguments. An attacker able to control those arguments could use this flaw to disclose portions of the application memory or cause it to crash.

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.

It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose source of scripts in the cgi-bin directory.

Solution

Run 'yum update python26' to update your system.
