Jakub Wilk reports:

Package: unshield
Version: 1.0-1
Tags: security

unshield is vulnerable to directory traversal via "../" sequences. As a 
proof of concept, unpacking the attached InstallShield archive creates a 
file in /tmp:

$ ls /tmp/moo
ls: cannot access /tmp/moo: No such file or directory

$ unshield x
 extracting: ./Bovine_Files/../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../../tmp/moo
--------  -------
         1 files

$ ls /tmp/moo

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Michael Orlitzky gentoo-dev 2016-08-25 15:02:40 UTC
This is still unresolved upstream:

I am going to commit a new version of this package anyway; then, when a fix is released, it should be easy to do another bump.
Comment 2 Michael Orlitzky gentoo-dev 2016-12-26 23:30:31 UTC
This is fixed in v1.4, which I've just added to the tree. I can remove the old versions after stabilization.
