- From CVE-2007-4131:
"The vulnerability is caused due to an input validation error when
extracting tar archives. This can be exploited to extract files to
arbitrary locations outside the specified directory with the permissions
of the user running GNU tar by using the ".." directory traversal
sequence in a specially crafted tar archive."
A patch is available in upstream CVS:
http://cvs.savannah.gnu.org/viewvc/tar/src/names.c?root=tar&r1=1.63&r2=1.64
The same portion of code is present also in versions 1.16 (stable) and
1.14 (oldstable), so this bug should be probably tracked and fixed there
too. However I'm not sure if there are other patches already applied
there to prevent this issue, so right now I'm reporting this bug for sid
only.
Cheers, Luca
