A security vulnerability was recently discovered by Peter Cock at the James
Hutton Institute that would allow a malicious actor to upload new versions
to repositories on which they have not been granted access.


This issue affects versions of the Tool Shed beginning with 15.01. Earlier
versions are not affected.


Because the Tool Shed is used to install software in Galaxy, if exploited,
the impact could result in arbitrary code execution on Galaxy servers if a
malicious tool is uploaded to a previously trusted repository, and that
compromised version is subsequently installed by a Galaxy administrator. As
such, Tool Shed administrators are strongly encouraged to update


To apply the fix, first identify your current Galaxy release version using
the `git branch` or `hg branch` commands. If you are on a 'release_YY.MM'
branch, you can update with:

  % git pull


  % hg pull -u

The process above can also be used to update to the 15.07 release if you
are on the 'master' git branch or the 'stable' hg branch. If you are on the
'master'/'stable' branch and wish to remain on your current Galaxy major
release, check the 'lib/galaxy/version.py' file to determine your major
release version, then update to the appropriate branch:

  % git checkout -b release_YY.MM origin/release_YY.MM
  % git pull


  % hg pull
  % hg update release_YY.MM

For the changes to take effect, YOU MUST RESTART ALL TOOL SHED SERVER
