WinSig.exe in eSignal 10.6.2425 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) a long StyleTemplate element in a QUO, SUM or POR file, which triggers a stack-based buffer overflow, or (2) a long Font->FaceName field (aka FaceName element), which triggers a heap-based buffer overflow. NOTE: some of these details are obtained from third party information.

Security readout for executives and security teams

CVE-2011-3494 affects WinSig.exe in eSignal 10.6.2425 and earlier. A maliciously oversized field in certain eSignal files can crash the application and may allow code execution. Business risk is highest where legacy eSignal workstations process files from external or untrusted sources. Exposure is likely limited to endpoints running eSignal 10.6.2425 or earlier, especially users who open QUO, SUM, or POR files. The source bundle does not identify server-side exposure, supported versions, or a confirmed vendor patch. Prioritize assessment where eSignal is used in trading or market-data workflows. The potential code execution language raises risk, but limited affected-product detail and no KEV evidence make this a targeted legacy-software remediation item, not a confirmed active-exploitation emergency. Mitigation focus: Identify and remove or upgrade eSignal 10.6.2425 and earlier where possible.; Check vendor guidance for fixed versions or supported migration paths.; Block or quarantine untrusted QUO, SUM, and POR files..
