USN-3132-1: tar vulnerability

21 November 2016

tar could be made to overwrite files.



  • tar - GNU version of the tar archiving utility


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
Ubuntu 16.04
Ubuntu 14.04
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
