Amazon Linux AMI : glibc (ALAS-2012-39)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way the glibc library read timezone files. If a
carefully-crafted timezone file was loaded by an application linked
against glibc, it could cause the application to crash or,
potentially, execute arbitrary code with the privileges of the user
running the application. (CVE-2009-5029)

A denial of service flaw was found in the remote procedure call (RPC)
implementation in glibc. A remote attacker able to open a large number
of connections to an RPC service that is using the RPC implementation
from glibc, could use this flaw to make that service use an excessive
amount of CPU time. (CVE-2011-4609)
