CVE-2022-30524 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. There is an invalid memory access in the TextLine class in TextOutputDev.cc in Xpdf 4.0.4 because the text extractor mishandles characters at large y coordinates. It can be triggered by (for example) sending a crafted pdf file to the pdftotext binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.. EPSS estimates a 1.59% chance of exploitation in the next 30 days.
