Thanks for working up this patch!
This has been fixed in Debian and the fixed version will appear soon in
Lucid. If an updated version for earlier releases (except Hardy) is

For Hardy, since the stack
I can reproduce this crash with unace-nonfree (but not with unace) on
amd64. So this bug should be reassigned to unace-nonfree.
Extracting works (unace x acev2.ace), but listing the contents crashes:
$ unace l ./acev2.ace

Comment #8 is wrong, the last part should read:
Is it possible that the bug was actually detected by using unace-
nonfree?
The good news is I managed to find the problem and have attached the
patch for unace-nonfree.
As Michael states in #12, it is the listing of the archive that fails,
not the
P Stahlman, I am unable to crash unace using your reproducer. I tried on both

I have been able to recreate the problem on several ace files using package
unace-nonfree, but not when using package unace.
Is it possible that the bug was actually detected by using unrar-nonfree?
The good news is I managed to find the problem and have attached the
patch for unace-free.

As you were able to reproduce this, can you give steps how to build an
archive to reproduce this? Or even attach one?

Here is a tiny archive with one file in it. The file name is very long,
triggering the buffer overrun.
(I created it on a windows machine using winace, not sure if we can
create ace archives under unix)

Is there any way, I can debug this further without providing the full ace
archive?
If I can find the section of the ace archive that is causing the crash, maybe I
can create an ace archive that will do.

Can you run apport on the crash file (check if one exists in
/var/crash/) so we can get a backtrace or provide a useful backtrace
yourself?
