Description Agostino Sarubbo gentoo-dev 2015-11-03 10:20:07 UTC
From ${URL} :

An unauthorized privilege escalation was found in sudoedit when a user is granted with root access 
to modify a particular file that could be located in a subset of directories. It seems that 
sudoedit does not check the full path if a wildcard is used twice (e.g. /home/*/*/file.txt), 
allowing a malicious user to replace the file.txt real file with a symbolic link to a different 
location (e.g. /etc/shadow), which results into unauthorized access. Affected versions are <= 

Reproducer can be found here:

@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.
