APPLE-SA-2009-09-09 Bonjour for Windows 1.0.5

Bonjour for Windows 1.0.5 is now available and addresses the
following issues:

mDNSResponder
CVE-ID:  CVE-2008-2326
Available for:  Windows Vista, XP SP2 and SP3, 2003, 2000
Impact:  Resolving a maliciously crafted ".local" domain name may
cause an unexpected application termination
Description:  A null pointer dereference issue exists in the Bonjour
Namespace Provider. Resolving a maliciously crafted ".local" domain
name containing a long DNS label may cause an unexpected application
termination. This update addresses the issue by performing additional
validation of DNS labels. This issue does not affect systems running
Mac OS X. Credit to Mario Ballano of 48bits.com for reporting this
issue.

mDNSResponder
CVE-ID:  CVE-2008-3630
Available for:  Windows Vista, XP SP2 and SP3, 2003, 2000
Impact:  mDNSResponder may return forged information for unicast DNS
queries
Description:  Bonjour for Windows provides Zero Configuration
Networking, Multicast DNS, and Network Service Discovery for Windows
users. It's also possible to use the Bonjour API to issue
conventional unicast DNS queries. A weakness in the DNS protocol may
allow a remote attacker to spoof DNS responses. As a result, if there
are applications that use Bonjour for Windows for unicast DNS, those
applications may receive forged information. However, there are no
known applications that use the Bonjour APIs for unicast DNS hostname
resolution. This update addresses the issue by implementing source
port and transaction ID randomization to improve resilience against
spoofing attacks. This change does not affect Multicast DNS
resolution.

Bonjour for Windows 1.0.5 is included in iTunes 8.0.
