What it is

SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, untrusted document paths and PDF link targets are interpolated into notification text that ParseTip() interprets as trusted tip markup. When a user clicks an injected link, ExecuteTipLink() dispatches its CmdExec command and can execute an attacker-selected local program in the user's context. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.
