script_tag(name:"insight", value:"When sudo is configured to allow a user to edit files under a directory that they can already write to without using sudo, they can actually edit (read and write) arbitrary files. Daniel Svartman reported that a configuration like this might be introduced unintentionally if the editable files are specified using wildcards, for example:
operator ALL=(root) sudoedit /home/*/*/test.txt
The default behaviour of sudo has been changed so that it does not allow editing of a file in a directory that the user can write to, or that is reached by following a symlink in a directory that the user can write to. These restrictions can be disabled, but this is strongly discouraged.
For the oldstable distribution (wheezy), this problem has been fixed in version 1.8.5p2-1+nmu3+deb7u1.
For the stable distribution (jessie), this problem has been fixed in version 1.8.10p3-1+deb8u3.
For the testing distribution (stretch), this problem has been fixed in version 1.8.15-1.1.
For the unstable distribution (sid), this problem has been fixed in version 1.8.15-1.1.
We recommend that you upgrade your sudo packages.");
