Background

c-ares is an asynchronous resolver library.

Description

It was discovered that c-ares incorrectly handled certain DNS requests.

Impact

A remote attacker, able to trigger a DNS request for a host of their choice by an application linked against c-ares, could possibly cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All c-ares users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-dns/c-ares-1.17.1"
OSVersionArchitecturePackageVersionFilename
Gentooanyallnet-dns/c-ares< 1.17.1UNKNOWN
