CVE-2011-0101 is a critical memory corruption vulnerability in Microsoft Excel 2002 SP3, allowing remote attackers to execute arbitrary code or cause a denial of service. This flaw stems from an incorrect pointer calculation when processing crafted RealTimeData records, specifically involving the stTopic field and double-byte characters. With a CVSS score of 9.3, it presents a high-severity risk due to its network-based attack vector, low authentication requirements, and complete compromise potential for confidentiality, integrity, and availability.
