tar vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Summary:
tar could be made to overwrite files.
Software Description:
- tar: GNU version of the tar archiving utility
Details:
Harry Sintonen discovered that tar incorrectly handled extracting files
when path names are specified on the command line. If a user or automated
system were tricked into processing a specially crafted archive, an
attacker could possibly overwrite arbitrary files.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.10:
tar 1.29b-1ubuntu0.1
Ubuntu 16.04 LTS:
tar 1.28-2.1ubuntu0.1
Ubuntu 14.04 LTS:
tar 1.27.1-1ubuntu0.1
Ubuntu 12.04 LTS:
tar 1.26-4ubuntu1.1
In general, a standard system update will make all the necessary changes.
