USN-506-1: tar vulnerability

28 August 2007

tar vulnerability

Releases

Packages

Details

Dmitry V. Levin discovered that tar did not correctly detect the ".."
file path element when unpacking archives. If a user or an automated
system were tricked into unpacking a specially crafted tar file, arbitrary
files could be overwritten with user privileges.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.04
Ubuntu 6.10
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
