Summary

Multiple vulnerabilities have been fixed in nano. 


Description
===========

CVE-2010-1160: 

GNU nano before 2.2.4 does not verify whether a file has  been  changed 
before it is overwritten in a file-save operation, which  allows  local 
user-assisted attackers to overwrite  arbitrary  files  via  a  symlink 
attack on an attacker-owned file that is being edited by the victim. 



CVE-2010-1161: 

Race condition in GNU nano before 2.2.4, when run by root to edit a file
that is not owned by root,  allows  local  user-assisted  attackers  to 
change the ownership of arbitrary files  via  vectors  related  to  the 
creation of backup files. 


Affected packages:

  Pardus 2009:
    nano, all before 2.2.4-21-10


Resolution
==========

There are update(s) for nano. You can update them via Package Manager or
with a single command from console: 

    pisi up nano
