What is CVE-2004-0445?

The SYMDNS.SYS driver in various Symantec Norton products is susceptible to a denial of service condition due to a flaw in how it handles DNS responses. A remote attacker can exploit this vulnerability by sending a specially crafted DNS response containing a compressed name pointer that erroneously points to itself. This can lead to excessive CPU consumption as the affected system enters an infinite loop, potentially disrupting services and impacting system performance.
