Description Vincent Danen 2012-02-10 04:19:26 UTC

A Debian bug report [1] indicated that surf would create the cookies storage file with world readable permissions.  This could allow other local users to steal cookies if the user had non-default permissions on their home directory (by default, home directories are mode 0700 but may be 0755 in some cases, like for Apache user directories).

$ ls -al ~/.surf/
total 12
drwxr-xr-x.  2 parallels parallels 4096 Feb  9 21:14 .
drwx------. 22 parallels parallels 4096 Feb  9 21:14 ..
-rw-rw-r--.  1 parallels parallels  312 Feb  9 21:14 cookies.txt
