CVE-2025-43718
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.
Does this matter?
Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.
Description
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).
