CVE-2022-37050

In Poppler 22.07.0, PDFDoc::savePageAs in PDFDoc.c callows attackers to cause a denial-of-service (application crashes with SIGABRT) by crafting a PDF file in which the xref data structure is mishandled in getCatalog processing. Note that this vulnerability is caused by the incomplete patch of CVE-2018-20662.

PATCH

referenced in comment 0
TW/poppler has this already in, but also fixed some resource leaks:
   if (!catObj.isDict()) {
        fclose(f);
        delete yRef;
        delete countRef;
        delete outStr;
        error(errSyntaxError, -1, "XRef's Catalog is not a dictionary");
        return errOpenFile;
    }
all versions needs the patch
