Foxit PDF Reader before 4.2.0.0928 does not properly bound-check the /Title entry in the PDF Info dictionary. A specially crafted PDF with an overlong Title string can overflow a fixed-size stack buffer, corrupt the Structured Exception Handler (SEH) chain, and lead to arbitrary code execution in the context of the user who opens the file.
STIGQter is an open-source reimplementation of DISA's STIG Viewer. From 0.1.2 to before 1.2.7, an attacker can achieve local code execution (LCE) with the privileges of the user running STIGQter. This requires user interaction: the victim must open the malicious .stigqter file and explicitly run the "Export HTML" action. This vulnerability is fixed in 1.2.7.
