Arch Linux Security Advisory ASA-201508-7
========================================
Severity: Low
Date    : 2015-08-16
CVE-ID  : CVE-2014-8121
Package : glibc
Type    : denial of service
Remote  : Yes
Link    : https://wiki.archlinux.org/title/CVE

Summary
======
The package glibc before version 2.22-1 is vulnerable to denial of service.

Resolution
=========
Upgrade to 2.22-1.

# pacman -Syu "glibc>=2.22-1"

The problem has been fixed upstream in version 2.22.

Workaround
=========
None.

Description
==========
It was found that the files backend 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.

Impact
=====
A remote attacker might be able to force a vulnerable application to
enter an infinite loop, thus causing denial of service.
