Amazon Linux AMI : libproxy (ALAS-2012-140)

critical Nessus Plugin ID 69630

Language:

Synopsis

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

Description

A buffer overflow flaw was found in the way libproxy handled the downloading of proxy auto-configuration (PAC) files. A malicious server hosting a PAC file or a man-in-the-middle attacker could use this flaw to cause an application using libproxy to crash or, possibly, execute arbitrary code, if the proxy settings obtained by libproxy (from the environment or the desktop environment settings) instructed the use of a PAC proxy configuration. (CVE-2012-4505)

Solution

Run 'yum update libproxy' to update your system.
