Comment 2 Jan Lieskovsky 2009-04-01 19:27:23 UTC
A buffer overflow flaw was found in Ghostscript's BaseFont writer module
for pdfwrite device. An attacker could create a specially-crafted Postscript file
which could cause ps2pdf to crash, or, potentially execute arbitrary
code, when ps2pdf was used to convert it to equivalent PDF file.
