Ubuntu Security Notice USN-191-1
29th September, 2005
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 5.04
- Ubuntu 4.10
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 5.04:
- Ubuntu 4.10:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
