What is CVE-2022-38349?

In the Poppler PDF Rendering Library version 22.08.0, a vulnerability has been identified in the Object.h file. A reachable assertion occurs within the PDFDoc::replacePageDict function, which lacks proper checks for streams before attempting to save an embedded file. This oversight can lead to a denial of service, potentially causing applications dependent on Poppler to crash or become unresponsive when processing specific PDF documents. Proper updates and safeguards are required to mitigate this issue and ensure robust PDF handling.
