Background

  1  dev-util/mercurial     < 1.0.1-r2                     >= 1.0.1-r2

Description
===========

Jakub Wilk discovered a directory traversal vulnerabilty in the
applydiff() function in the mercurial/patch.py file.

Impact

outside the repository.

Workaround
==========

There is no known workaround at this time.

Resolution
