Description

The remote host is affected by the vulnerability described in GLSA-200508-08 (Xpdf, Kpdf, GPdf: Denial of Service vulnerability)

Xpdf, Kpdf and GPdf do not handle a broken table of embedded     TrueType fonts correctly. After detecting such a table, Xpdf, Kpdf and     GPdf attempt to reconstruct the information in it by decoding the PDF     file, which causes the generation of a huge temporary file.

Impact :

A remote attacker may cause a Denial of Service by creating a     specially crafted PDF file, sending it to a CUPS printing system (which     uses Xpdf), or by enticing a user to open it in Xpdf, Kpdf, or GPdf.

Workaround :

There is no known workaround at this time.
