Description Josh Bressers 2008-12-03 21:54:20 UTC
chm2pdf 0.9 allows user-assisted local users to delete arbitrary files via a symlink attack on .chm files in the (1) /tmp/chm2pdf/work or (2) /tmp/chm2pdf/orig temporary directories.

Let's try this again.  chm2pdf in Fedora 14 is still vulnerable to this.  A
patch was provided in the Debian bug:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=501959#20

I can't think of a reason not to use it.
