Amazon Linux AMI : glibc (ALAS-2015-495)

medium Nessus Plugin ID 82044

Language:

Synopsis

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

Description

An out-of-bounds read flaw was found in the way glibc's iconv() function converted certain encoded data to UTF-8. An attacker able to make an application call the iconv() function with a specially crafted argument could use this flaw to crash that application.
(CVE-2014-6040)

It was found that the files back end of Name Service Switch (NSS) did not isolate iteration over an entire database from key-based look-up API calls. An application performing look-ups on a database while iterating over it could enter an infinite loop, leading to a denial of service. (CVE-2014-8121)

Solution

Run 'yum update glibc' to update your system.
