CVE-2019-9877

Published: 21 March 2019

There is an invalid memory access vulnerability in the function TextPage::findGaps() located at TextOutputDev.c in Xpdf 4.01, which can (for example) be triggered by sending a crafted pdf file to the pdftops binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.
