CVE-2006-2781 describes a double free vulnerability in Mozilla Thunderbird and SeaMonkey, specifically within the nsVCard.cpp component. This flaw allows remote attackers to trigger a denial of service (application hang) and potentially execute arbitrary code by sending a VCard containing invalid base64 characters. With a CVSS score of 6.4, it is considered a medium-severity vulnerability, requiring no authentication and low attack complexity. While no active exploitation, public exploit code, or significant community discussion has been observed, the potential for arbitrary code execution warrants attention.
