 Mandriva Linux Security Advisory                         MDKSA-2005:197
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : unzip
 Date    : October 26, 2005
 Affected: 10.1,  10.2,  2006.0,  Corporate 2.1,  Corporate 3.0,
           Multi Network Firewall 2.0
 _______________________________________________________________________
 
 Problem Description:
 
 Unzip 5.51 and earlier does not properly warn the user when 
 extracting setuid or setgid files, which may allow local users 
 to gain privileges. (CAN-2005-0602)
 
 Imran Ghory found a race condition in the handling of output files.
 While a file was unpacked by unzip, a local attacker with write
 permissions to the target directory could exploit this to change the
 permissions of arbitrary files of the unzip user. This affects
 versions of unzip 5.52 and lower (CAN-2005-2475)
 
 The updated packages have been patched to address these issues.
