CVE-2018-18651

Name of the Vulnerable Software and Affected Versions Xpdf version 4.00

Description An issue in the catalog->getNumPages() function in AcroForm.cc allows attackers to launch a denial of service attack, causing the system to hang due to a large loop, via a specific pdf file. This is mainly caused by a large number after the /Count field in the file.

Recommendations For Xpdf version 4.00, consider restricting the use of the catalog->getNumPages() function in AcroForm.cc until a patch is available to prevent potential denial of service attacks.
