What is CVE-2004-0842?
This vulnerability in Internet Explorer 6.0 SP1 and earlier versions allows remote attackers to exploit malformed CSS elements, leading to a denial of service through application crashes. The issue manifests from a heap-based buffer overflow, potentially triggered by an invalid length resulting from a missing comment terminator. Consequently, certain CSS strings can prompt extensive memory operations, severely impacting system stability.
