  • 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.

  • 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.
