Assigner: MITRE

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).

Executive Summary

This vulnerability in Poppler versions 24.06.1 through 25.x before 25.04.0 allows excessive stack consumption and causes a segmentation fault (SIGSEGV) due to deeply nested structures within the metadata of a PDF document. Specifically, it occurs in functions like Dict::lookup and Catalog::getMetadata when processing complex metadata such as a long pdfsubver string with regular expressions, leading to deep recursion in the regex executor.

Impact Analysis

The vulnerability can cause a program using the affected Poppler versions to crash unexpectedly due to stack overflow and segmentation faults when processing maliciously crafted PDF metadata. This can lead to denial of service or instability in applications relying on Poppler for PDF processing.
