Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion in the pdfConformanceFromString() function. Processing of deeply nested structures within PDF metadata, specifically in the Dict::lookup and Catalog::getMetadata functions, which leads to deep recursion in the regex executor. An attacker can cause stack exhaustion and application crash by supplying a crafted PDF document containing excessively nested metadata fields.
