CVE-2011-3494 describes a critical vulnerability in WinSig.exe within eSignal 10.6.2425 and earlier, allowing remote attackers to trigger denial of service or potentially execute arbitrary code. This is due to stack-based and heap-based buffer overflows when processing specially crafted QUO, SUM, or POR files with long StyleTemplate elements or Font->FaceName fields. With a CVSS score of 10.0, the vulnerability is easily exploitable over the network with low complexity and no authentication, leading to complete compromise of confidentiality, integrity, and availability. While not listed on the KEV catalog, exploit code, including a Metasploit module, is publicly available, indicating a high potential for exploitation despite limited community discussion or media coverage.
