[GLSA-200508-08] Xpdf, Kpdf, GPdf: Denial of Service vulnerability |
||
Xpdf, Kpdf, GPdf: Denial of Service vulnerability Detailed Explanation for this Vulnerability Assessment 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.
