Bug Description
Binary package hint: feh
Hi, I've just discovered that feh is vulnerable to rewriting any user file:
tmpname_
...
If attacker knows PID of feh and knows the URL, it can create the link to any user file. wget would overwrite it.
Thanks.

The latest release of Ubuntu is not vulnerable to symlink race attack, but earlier release will need fixing. https:/ /wiki.ubuntu. com/Security/ Features# symlink
