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.
