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.

Comment 2 Vincent Danen 2010-12-24 03:22:38 UTC

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.

Created chm2pdf tracking bugs for this issue

Affects: fedora-all [bug 665494]

Comment 4 Vincent Danen 2011-02-07 17:04:17 UTC

This flaw was corrected in Fedora 14:

chm2pdf-0.9.1-9.fc14 (FEDORA-2011-0454)

and Fedora 13:

chm2pdf-0.9.1-8.fc13 (FEDORA-2011-0467)
