Advisory: RHSA-2007:0674-3
Type: Security Advisory
Severity: Moderate
Issued on: 2007-07-12
Last updated on: 2007-07-12
Affected Products: Red Hat Desktop (v. 3)
Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux AS (v. 3)
Red Hat Enterprise Linux Desktop (v. 5 client)
Red Hat Enterprise Linux ES (v. 3)
Red Hat Enterprise Linux WS (v. 3)
CVEs (cve.mitre.org): CVE-2007-3377
CVE-2007-3409

Details

Updated perl-Net-DNS packages that correct two security issues are now
available for Red Hat Enterprise Linux 3 and 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Net::DNS is a collection of Perl modules that act as a Domain Name System
(DNS) resolver.

A flaw was found in the way Net::DNS generated the ID field in a DNS query.
This predictable ID field could be used by a remote attacker to return
invalid DNS data. (CVE-2007-3377)

A denial of service flaw was found in the way Net::DNS parsed certain DNS
requests. A malformed response to a DNS request could cause the application
using Net::DNS to crash or stop responding. (CVE-2007-3409)

Users of Net::DNS should upgrade to these updated packages, which contain
backported patches to correct these issues.


Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
