Last modified

CVE-2025-43718 is a low-severity vulnerability rated 2.9/10 on the CVSS scale. Poppler 24.06.1 through 25.x before 25.04.0 allows stack consumption and a SIGSEGV via deeply nested structures within the metadata (such as GTS_PDFEVersion) of a PDF document, e.g., a regular expression for a long pdfsubver string. This occurs in Dict::lookup, Catalog::getMetadata, and associated functions in PDFDoc, with deep recursion in the regex executor (std::__detail::_Executor).. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
