Name of the Vulnerable Software and Affected Versions Xpdf version 4.00

Description The issue allows remote attackers to cause a denial of service via a crafted pdf file.

The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited.
