security flaw

Buffer overflow in (1) gv 3.5.8 and earlier, (2) gvv 1.0.2 and earlier, (3) ggv 1.99.90 and earlier, (4) gnome-gv, and (5) kghostview in kdegraphics 2.2.2 and earlier, allows attackers to execute arbitrary code via a malformed (a) PDF or (b) PostScript file, which is processed by an unsafe call to sscanf.

gv 3.5.8, and possibly earlier versions, allows remote attackers to execute arbitrary commands via shell metacharacters in the filename for (1) a PDF file or (2) a gzip file.
